    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLORADO
    (D.C. No. 97-CR-110-B)
    Todd S. Welch (Bobac A. Barjesteh and William Perry Pendley, with him on the brief) of
    Mountain States Legal Foundation, Denver, Colorado, for Defendant-Appellant.

    Before PORFILIO, HOLLOWAY and TACHA, Circuit Judges.
    HOLLOWAY, Circuit Judge.
    Mr. Unser brings this timely, direct appeal from his conviction for unlawful
    possession and operation of a motor vehicle within a National Forest Wilderness Area in
    violation of 
    16 U.S.C. § 551
     and 
    36 C.F.R. § 261.16
    (a). The maximum penalty for this
    conduct is a sentence of up to six months of imprisonment, a fine of up to $5,000, or both.
    
    16 U.S.C. § 551
     (setting out length of imprisonment authorized and maximum fine of $500);
    
    18 U.S.C. § 3571
    (b)(6) (raising maximum fine to $5,000). The crime charged is a Class B
    misdemeanor (because the maximum authorized punishment is more than thirty days but no
    more than six months, 
    18 U.S.C. § 3559
    (a)(7)) and a “petty offense,” a category which
    includes misdemeanors of Classes B and C, plus “infractions,” 
    18 U.S.C. § 19.1
     After a
    two-day trial to the court, Unser was convicted and was sentenced to pay a fine of $75.
    This case arises from a story of survival in the wilderness under extreme conditions
    and involves legal issues requiring examination of some of the most fundamental concepts
    in criminal law. Like the parties obviously do, we view the case as having significance
    beyond the penalty actually imposed.
    I
    A
    We will begin with an overview of the facts. Our summary in this part of the opinion
    is based on the testimony of the defendant, who was the only witness at trial to have been
    present during the primary events. Much of this evidence was undisputed; we will note later
    1
    The significance of the petty offense category is that less stringent procedural rights
    are accorded to the accused who faces only charges of this type. See Fed. R. Crim. P. 58.
    Thus, most significantly, the accused does not have a right to a jury trial. Fed. R. Crim. P.
    58(b)(2)(F).
    -2-
    in the opinion the critical areas which are in dispute.
    On Friday, December 20, 1996, Mr. Unser set off to go snowmobiling with a friend,
    Robert Gayton. Unser, who lives in Albuquerque and has a ranch near Chama in far northern
    New Mexico, was very experienced with snowmobiles and fairly familiar with the place he
    chose for them to ride. Gayton had never been on a snowmobile before, and so took a few
    minutes to practice on the snowmobile at Unser’s ranch. The two then loaded two
    snowmobiles onto a trailer and made a short drive on state highways across the state line into
    far southern Colorado, high in the San Juan Range of the Rocky Mountains near La Manga
    Pass.
    They parked at the Red Lake Trail parking lot on state highway 17. From there, Unser
    planned a fairly short ride to the Jarosa Peak area of the Rio Grande National Forest. Unser
    planned on a fairly short ride for several reasons. It was already midday when they reached
    the parking lot to begin riding, and of course nightfall would come early at that time of the
    year. While Unser was a very experienced rider, he had only recently recovered from back
    surgery, and his companion, as we have noted, was a beginner.
    Gayton rode around a few minutes in the immediate area of the parking lot to get more
    familiar with the machine and to riding in the deeper snow at the higher elevation near the
    pass. The two then set off for the Jarosa Peak area. The area around this peak includes a
    mesa, sometimes referred to as Jarosa Mesa, which was a climb of a few hundred feet from
    the parking lot. Unser said he chose this place because it was a fairly short and easy, yet
    -3-
    interesting, ride for the beginner, Gayton.
    The weather was clear at first, but when the two men reached the mesa, Unser
    testified, a “ground blizzard” came up rather suddenly. A ground blizzard was described as
    the result of high winds blowing substantial amounts of fallen snow; these conditions may
    arise when no new snow is falling. Visibility was near zero. Unser’s machine started having
    problems (the engine died repeatedly for the rest of the ill fated ride), and the situation
    became dangerous. The two men got lost trying to find their way back to the truck. Then,
    Gayton went off into a small ravine and his machine was stuck. They abandoned it and rode
    on. As they did, they were continually having to work on Unser’s machine to get it restarted.
    Eventually, it failed completely. The men started walking but were still lost when night
    came. They dug a snow cave and spent the night in it. The next day they continued their
    wanderings on foot, suffering greatly. They hiked through the day and night until some time
    after midnight when they came upon a barn equipped with a telephone. They were soon
    rescued. They were treated at a local hospital for frostbite, dehydration and exhaustion.
    B
    We will now review other evidence presented at trial. While Mr. Unser and
    Mr. Gayton were lost in the rugged terrain of the National Forest battling the extreme cold
    and other adverse elements, friends and family were aware that they had not returned on
    Friday evening. On Saturday December 21 a search and rescue operation was organized.
    Some friends of Unser went up from Chama to the parking lot where his truck had been
    -4-
    noticed. On arriving there, they were told by a local deputy sheriff that they would have to
    wait for the authorized search and rescue team from Colorado to arrive, which they did.
    Eventually, six to eight people went out from the trail head on snowmobiles looking for
    Unser and Gayton.       The rescuers did not actually get out on the mountain until
    mid-afternoon, and so had only a couple of hours before nightfall. In that time they found
    the snowmobile that Gayton had been riding, but were unable to find enough tracks to
    determine which way the two men had gone from there.
    At trial four witnesses who had participated in the search and rescue operation
    testified. Only one of these witnesses, Richard Martin, was called by the government. Martin
    is a resident of southern Colorado and a veteran of a number of similar rescue efforts. Martin
    testified that the conditions were not bad on December 21 as the group began their search.
    The men were able to find tracks and, at least at first, to follow the path that Unser and
    Gayton had made the previous day. From the tracks, it appeared that Unser had started out
    from the parking lot on a fairly well defined trail, one which had in years past been used by
    cattlemen taking stock up to summer pastures. (We note at this point that all the witnesses
    at trial agreed that Unser’s ill fated ride had begun along this route, but opinions were
    divided on where he might have gone after the first five or six miles.) That trail led up to
    what the witnesses referred to as Jarosa Mesa (but it is not clear from the record just how far
    this area goes). Conditions up on the mesa were very bad, as visibility was greatly reduced
    by blowing snow.
    -5-
    Martin testified that he found tracks on the mesa which appeared to have been made
    when Unser and Gayton were merely riding for fun; at the judge’s suggestion, he marked
    “PT” on the enlarged map exhibit to show the area where he had found these “play tracks.”
    The rescuers attempted to follow Unser’s tracks from there, but tracking became very
    difficult because so many of the tracks had been erased by blowing snow by that time.
    Eventually, Martin found the snowmobile that Gayton had been riding. Martin testified that
    the tracks he had been following just before he found this first snowmobile indicated to him
    that the riders were lost and trying to find their way. The rescue team extricated the
    abandoned snow mobile and rode on, dividing into two groups. At nightfall, they suspended
    their efforts for the day.
    Martin marked on the map for the court the point where he estimated that the first
    snow mobile had been found and made a line to show the route he believed he had taken to
    this point. The route as drawn by Martin proceeds for slightly over three miles in a
    northwesterly direction, almost in a straight line from the point where Martin had marked
    “play tracks” on the map, and ends about two miles past the boundary of the wilderness area.
    This testimony was later cited by the trial judge as the most credible and consistent evidence
    as to the location of the first machine, an issue of fact which was of considerable significance
    because of other findings by the judge, as we shall see.
    It is worth noting that Martin’s testimony was far from precise. Martin was candid
    in describing his effort as being less than certain, twice describing it as a guess. When the
    -6-
    rescuers split into groups after having found the first abandoned snowmobile, Martin had
    ridden to Red Lake, which was northeast of the point he marked on the map as the likely
    location of the first machine. Martin testified that his estimate of the location of the
    snowmobile was based in part on his belief that he had been going northeast from that point
    to Red Lake during the rescue efforts.
    Martin had gone back to the area only a few days before trial in the company of Forest
    Service Agent Burd, among others, to see if he could retrace the path he had taken during the
    rescue effort. Martin testified that they were very careful to stay out of the Wilderness Area
    and stopped before reaching the place where Martin believed the first snow mobile had been
    found. (Although it was June when this effort was made, they were on snowmobiles.) As
    the defense has emphasized, both at trial and on appeal, Martin said that the odometer on his
    snowmobile read 7.2 miles when he turned back at a point he (or others with him) estimated
    to have been about a quarter of a mile short of the wilderness boundary.2 Martin also
    testified that during this second visit to the area he tested his sense of direction and found that
    he was off by eighty degrees. He was not asked to explain whether he had accounted for this
    when he testified that he believed that the first snowmobile had been found southwest of Red
    Lake.
    It is interesting to note that on this second visit to the area, Mr. Martin had the
    2
    advantage of much better weather conditions and the assistance of maps and guidance from
    the Forest Service. Even so, he was uncertain just where the wilderness boundary was and
    said that he had never seen signs in this area marking the boundary.
    -7-
    C
    About three weeks after this adventure, Unser contacted officials with the Forest
    Service’s office in Albuquerque for assistance in finding the second snowmobile. Unser met
    with Ben Tafoya, a Forest Service Agent, on January 7, 1997, in Albuquerque. Because he
    had been told that he might need a permit to retrieve the machine, Unser brought with him
    a friend, Gabe Valdez, and Manny Martinez. Before retiring, Manny Martinez had been a
    supervisor in the law enforcement unit of the Forest Service and indeed had formerly been
    Tafoya’s immediate supervisor. These men met and went over maps trying to determine
    where the machine might have been abandoned, but they believed that they had accomplished
    little. Further efforts were planned for the next day.
    Tafoya told Unser that he would contact officials with the Colorado offices of the
    Forest Service who would be more familiar with the area and of more assistance. When
    Tafoya first contacted officials in Colorado, he asked to speak to Chris Ortiz, the law
    enforcement officer for that area. Ortiz told Tafoya that he should speak with Brenda Schultz
    or Charlie Burd, who were investigating the incident for possible violation of the ban on use
    of motor vehicles in a wilderness area, having determined that Unser probably had entered
    the South San Juan Wilderness Area of the Rio Grande National Forest. Those two agents,
    Burd and Schultz, arranged to come to meet with Unser at Tafoya’s office the following day.
    Tafoya was asked not to tell Unser that these officers wanted to talk to him as part of their
    criminal investigation. Instead, Tafoya merely told Unser that two agents were coming down
    -8-
    from Colorado who could help him locate and retrieve his snowmobile.
    Charlie Burd, special agent with the Forest Service, testified that he, along with
    Brenda Schultz, met with Unser the next day for about three and a half hours in a conference
    room near Tafoya’s office in Albuquerque. Unser came by himself to this meeting. Burd
    indicated that Unser was mostly cooperative during this meeting, but Burd suggested that
    Unser was less than candid at times in saying that he had no idea which way he had gone
    after leaving Jarosa Mesa. After lengthy and not very productive discussions, Burd asked
    Unser to draw a sketch of the valley where the second machine had been abandoned. From
    this sketch, Burd testified he was able to recognize the area. Burd then showed Unser an
    aerial phoptograph, using a stereoscopic device to give the photo a three dimensional effect.
    Unser immediately recognized the photograph Burd had selected. Six months later, just the
    week before trial, Burd located the second machine, still stuck in the snow, very near the
    place that he and Unser had identified in the January meeting. Burd marked that point on the
    topographical map that Martinez had used in his testimony, government’s exhibit 3. The
    point is almost due east of the point identified by Martinez as the most likely location of the
    recovery of the first machine.
    Burd testified that Unser never indicated to him that he had any concern for his safety
    until the second snowmobile failed. Unser had said that he had been in this area about ten
    times before, but that he was unsure just where they had gone because he simply had not
    been paying attention while he was enjoying the sport. According to Burd’s testimony, Unser
    -9-
    told him that after the first machine got stuck, with the weather beginning to be bad, Unser
    decided to try to head straight back to the parking lot, rather than to return by retracing their
    path. Unser had told Tafoya that at that point he started following the “windrows.”
    Windrows are wave like patterns in the snow which, Tafoya testified, would generally run
    east to west in this area.
    D
    As for the defense evidence, for purposes of our review we need not go into any
    detail. The trial judge clearly did not find much of the defendant’s evidence on critical issues
    to be credible. It is sufficient to note that two members of the rescue team attempted to
    locate on the map the point where they thought the first snowmobile had been recovered, and
    like defendant in his testimony, both fixed this point as being outside the wilderness area,
    before Unser and Gayton would have reached the wilderness boundary. Matthew Martinez
    testified that he was among those who went back to the area on Sunday, December 22, after
    Unser and Gayton had been rescued, to retrieve the first snowmobile. He said that the
    snowmobile’s odometer showed eight miles plus some tenths. Several witnesses agreed that
    a snowmobile’s odometer usually shows more miles than has actually been traveled. This
    is because the odometer registers revolutions of the track, which often slips especially when
    the rider is attempting to climb a steep slope. Mr. Burd testified that the route apparently
    taken by Unser up to the top of Jarosa Mesa was so steep that when he made the climb
    himself he thought at first that his machine would not be able to do it.
    - 10 -
    II
    On appeal from a criminal conviction, of course, we view the evidence in the light
    most favorable to the prosecution. In the instant case, where the trial judge found the facts
    specially, even though not requested to do so,3 the findings may not be disturbed unless
    clearly erroneous. Campbell v. United States, 
    373 U.S. 487
    , 493 (1963).
    We will summarize the district judge’s findings as a prelude to our analysis of the
    legal issues raised by Mr. Unser. Although there is essentially no dispute as to the main
    events as described by Unser and as we have just summarized, there certainly was dispute
    about important details. The trial judge did not credit Unser’s testimony in its entirety. In
    particular, the judge found that the two riders left the Jarosa Peak area before any emergency
    arose and that they were intentionally riding northwest, further away from where they had
    begun their ride, because they were still just riding for fun.
    The judge found that Mr. Martin’s testimony as to the location of the first snowmobile
    was the most credible, and he gave several reasons for this finding. The fact that the second
    machine was eventually recovered almost due east from where Mr. Martin fixed the location
    of the first machine was consistent with the Unser’s statements, both in the interview with
    Burd and in his trial testimony, that after abandoning the first machine he and Gayton
    In the trial of a criminal case without a jury, the judge must make a general finding
    3
    and “shall in addition, on request before the general finding, find the facts specially.”
    Fed. R. Crim. P. 23(c). The findings may be oral or may be stated in an opinion or
    memorandum of decision.
    - 11 -
    attempted to follow the windrows, which the evidence established ran west to east. The
    judge found that the odometer reading on the first machine, when it was recovered, was a
    little over eight miles. The judge then said that he had used a piece of wire to determine the
    distance to the spot on the map marked by Mr. Martin, following the route Martin had said
    that rescuers had used in following the tracks left by Unser and Gayton. From this
    examination of the evidence, the judge determined that it was about 4.2 miles from the
    parking lot to the place which Martin had estimated to be the location of the abandoned first
    snowmobile. (In fact, the judge misread the scale of the map; the distance is twice what he
    found it to be. This is clear because he made findings about other points on the map, each
    of which is plainly based on the same erroneous reading of the scale of miles.)
    The judge then proceeded to consider Unser’s contention that if he had entered the
    wilderness area with a snowmobile, he had done so only under a life-threatening emergency.
    The judge had held before trial that Unser would have the burden of proving this defense by
    a preponderance of the evidence. This conclusion was based on another holding made before
    trial, i.e., that the offense charged was a strict liability offense and accordingly the
    government would not have to prove any intent to snowmobile in the wilderness area, nor
    would the government have to prove that Unser knew that he had entered a wilderness area.
    The judge stated, “[T]he law ought to afford, and I believe does, a measure of defense to the
    citation issued here based upon emergency and defenses otherwise known essentially as a
    necessity defense, sometimes called a choice of evils defense.” II App. at 687.
    - 12 -
    Accordingly, in the judge’s view it was critical to determine whether emergency
    conditions had arisen before or after Unser had entered the wilderness area. The judge
    specifically found that an emergency did not arise until “either just before or just after Mr.
    Gayton’s machine got stuck.” II App. at 689. Based on his finding that the more credible
    evidence was that the first machine had been found inside the wilderness boundary, the judge
    concluded and held that the defense had failed to carry the burden of establishing the
    necessity defense, and pronounced the defendant guilty.
    This appeal followed. The major contentions of defendant Unser on appeal are: (1)
    the district judge erred by holding that the offense of violation of 
    16 U.S.C. § 551
     and 
    36 C.F.R. § 261.16
    (a) of possessing and using a motor vehicle in a Wilderness Area contains
    no mens rea requirement; (2) the judge erred by denying defendant Unser the necessity
    defense in the emergency conditions that confronted Unser and his companion; and (3) the
    judge erred in denying defendant Unser’s motion to suppress his statement based on the
    involuntariness of the statement and violation of his rights under the Miranda doctrine.
    We will analyze these issues in turn.
    III
    First, we address the mens rea issue:
    “Few areas of criminal law pose more difficulty than the proper definition of the
    mens rea required for any particular crime.” United States v. Bailey, 
    444 U.S. 394
    , 403
    (1980). Our task is to determine, as best we can, the intent of Congress in empowering the
    - 13 -
    Secretary of Agriculture to adopt regulations applicable to National Forest lands and
    enforceable by criminal penalties. Then, having found that intent, we must determine
    whether the intent is compatible with due process. Unfortunately, we find little direct
    guidance in the language Congress used.4 The regulation promulgated by the Secretary of
    Agriculture likewise reveals little on this question.5 However, while the statute and
    regulation involved here do not contain a mens rea element, “silence on this point by itself
    does not necessarily suggest that the [legislators] intended to dispense with a conventional
    
    16 U.S.C. § 551
     provides, in pertinent part:
    4
    The Secretary of Agriculture shall make provisions for the protection
    against destruction by fire and depredations upon the public forests and
    national forests which may have been set aside or which may be hereafter set
    aside . . . and he may make such rules and regulations and establish such
    service as will insure the objects of such reservations, namely, to regulate their
    occupancy and use and to preserve the forests thereon from destruction; and
    any violation of the provisions of this section . . . or such rules and regulations
    shall be punished by a fine of not more than $500 or imprisonment for not
    more than six months, or both.
    As noted earlier, Congress changed the maximum fine from $500 to $5,000 in 1987.
    See 
    18 U.S.C. § 3571
    (b)(6). Thus, at the time of this offense in 1996, the maximum penalties
    to which Mr. Unser could have been sentenced were a fine of not more than $5,000, or
    imprisonment for not more than six months, or both.
    The regulation under which Mr. Unser was prosecuted provides:
    5
    The following are prohibited in a National Forest Wilderness:
    (a) Possessing or using a motor vehicle, motorboat or motorized
    equipment except as authorized by Federal Law or regulation.
    
    36 C.F.R. § 261.16
    - 14 -
    mens rea element.” Staples v. United States, 
    511 U.S. 600
    , 605 (1994); Morissette v. United
    States, 
    342 U.S. 246
    , 263 (1952); United States v. Martinez-Morel, 
    118 F.3d 710
    , 716
    (10th Cir. 1997).
    Morissette also noted, however, that the general presumption that some guilty purpose
    is required is not applicable to what have been termed public welfare offenses, which
    typically impose penalties to serve as an effective means of regulation. The Court’s
    observations about the nature of such public welfare offenses provide a helpful starting point
    for our analysis:
    These cases do not fit neatly into any of such accepted classifications of
    common-law offenses, such as those against the state, the person, property, or
    public morals. Many of these offenses are not in the nature of positive
    aggressions or invasions, with which the common law so often dealt, but are
    in the nature of neglect where the law requires care, or inaction where it
    imposes a duty. Many violations of such regulations result in no direct or
    immediate injury to person or property but merely create the danger or
    probability of it which the law seeks to minimize. While such offenses do not
    threaten the security of the state in the manner of treason, they may be
    regarded as offenses against its authority, for their occurrence impairs the
    efficiency of controls deemed essential to the social order as presently
    constituted. In this respect, whatever the intent of the violator, the injury is the
    same, and the consequences are injurious or not according to fortuity. Hence,
    legislation applicable to such offenses, as a matter of policy, does not specify
    intent as a necessary element. The accused, if he does not will the violation,
    usually is in a position to prevent it with no more care than society might
    reasonably expect and no more exertion than it might reasonably exact from
    one who assumed his responsibilities. Also, penalties commonly are relatively
    small, and conviction does no grave damage to an offender’s reputation.
    Under such considerations, courts have turned to construing statutes and
    regulations which make no mention of intent as dispensing with it and holding
    that the guilty act alone makes out the crime.
    Morissette, 
    342 U.S. at 255-56
     (emphasis added).
    - 15 -
    Following Morissette, the Eighth Circuit has stated that
    where a federal criminal statute omits mention of intent and where it seems to
    involve what is basically a matter of policy, where the standard imposed is,
    under the circumstances, reasonable and adherence thereto properly expected
    of a person, where the penalty is relatively small, where the conviction does
    not gravely besmirch [the reputation], where the statutory crime is not one
    taken over from the common law, and where congressional purpose is
    supporting, the statute can be construed as one not requiring criminal intent.
    The elimination of this element is then not violative of the due process clause.
    Holdridge v. United States, 
    282 F.2d 302
    , 310 (8th Cir. 1960)(Blackmun, J.); see also Tart
    v. Massachusetts, 
    949 F.2d 490
    , 502 (1st Cir. 1991). Additionally, the Supreme Court has
    indicated that most public welfare offenses involve situations where a reasonable person
    should know that the conduct is subject to stringent regulation and may seriously threaten a
    community’s health or safety. Liparota v. United States, 
    471 U.S. 419
    , 433 (1985).
    The government contends, and we agree, that the regulation at issue here satisfies
    most of these criteria, conceding however that the conduct in question does not seem to
    seriously threaten a community’s health or safety. The government states: “Admittedly, it
    is difficult [to] characterize the use of motorized vehicles in a wilderness area as conduct
    ‘that may seriously threaten a community’s health or safety.’” Brief of Appellee at 14
    (quoting Liparota v. United States, 
    471 U.S. 419
    , 433 (1985)).         Nevertheless, we are
    persuaded that 
    16 U.S.C. § 551
     and 
    36 C.F.R. § 261.16
    (a), the applicable statute and
    regulation involved here, do create a “public welfare offense.” Indeed, several other courts
    have found that such Forest Service regulations define public welfare offenses. E.g., United
    States v. Kent,

    (D. Utah 1998) (mental element required for offense of allowing unauthorized livestock to
    enter National Forest).
    We must decide the effect of the omission from the statute and regulation of a
    mens rea requirement. Under the proposition distilled by Justice Blackmun’s Holdridge
    opinion for the Eighth Circuit from earlier cases, 242 F.2d at 310, we are persuaded that most
    of the conditions are met for treating the offense charged here as a public welfare offense
    lacking a mens rea requirement: there is, as noted, no mention of an intent in the statute or
    regulation; the duty imposed is reasonable, under the circumstances, and adherence properly
    expected; the statutory scheme is not one taken from the common law and congressional
    purpose is supportive; and conviction does not gravely besmirch one’s reputation, involving
    only a misdemeanor. The troublesome question remaining is whether “the penalty is
    relatively small.” Holdridge, 
    282 F.2d at 310
    .
    Taking into account the 1987 increase in the potential fine, the maximum penalties
    - 17 -
    are a $5,000 fine, or imprisonment for not more than six months, or both. These are not
    de minimis, in our judgment, but the test is whether “the penalty is relatively small,” as
    Holdridge, 
    282 F.2d at 310
     (emphasis added), states. This follows the test laid down by the
    Supreme Court in Morissette, that “penalties commonly are relatively small,” 
    342 U.S. at 256
    (emphasis added), for public welfare offenses where no mention of intent is made and the
    guilty act alone makes out the crime. In Staples, the Court noted that cases that first defined
    the concept of public welfare offenses involved statutes that “punished only light penalties
    such as fines or short jail sentences . . . .” 
    511 U.S. at 616
    .6 Later Staples referred to “small
    penalties” being attached to such public welfare offenses as logically complementing the
    absence of a mens rea requirement. 
    Id.
     (emphasis added). We have addressed a similar issue
    in United States v. Corrow, 
    119 F.3d 796
    , 805 (10th Cir. 1997), cert. denied, 
    118 S. Ct. 1089
    (1998), in the context of Migratory Bird Treaty Act misdemeanor violations carrying a
    potential fine up to $5,000 or imprisonment of not more than six months, or both. See 
    16 U.S.C. § 707
    (a) and 
    18 U.S.C. § 3571
    (b) (raising maximum fine up to $5,000 in 1987). In
    Corrow, we joined other circuits in holding such offenses are strict liability without a scienter
    requirement.
    This 1996 offense occurred in a time frame when heavier sentences of imprisonment
    6
    In Staples, the Court cited Commonwealth v. Raymond, 
    97 Mass. 567
     (1867)(fine up
    to $200 or six months in jail, or both); Commonwealth v. Farrer, 
    91 Mass. 489
     (1864)(fine);
    and People v. Snowburger, 
    71 N.W. 497
     (Mich. 1897)(fine up to $500 or incarceration in
    county jail).
    - 18 -
    and fines are more common. In light of these circumstances and the lack of besmirching an
    offender’s reputation by a felony conviction, we are persuaded that the public welfare offense
    in question here was properly held by the district judge not to have a required mens rea
    element.
    IV
    As we have earlier noted, the district judge held that Unser could assert a common law
    defense of necessity, based on the life threatening situation he faced when he became lost in
    the extreme conditions that have been described. The judge eventually ruled, however, that
    Unser had not carried the burden of proving the necessity defense by a preponderance of the
    evidence. Unser argues on appeal that the district judge erred in holding that he had the
    burden of proof on the necessity defense,7 and also argues that the evidence showed that any
    entry into the wilderness area should have been excused under the necessity defense.
    We have discussed the necessity defense on several occasions. It is well settled, and
    not challenged here, that the defendant at least must bear the initial burden of producing
    evidence which could support a finding in his favor on each element of the defense. The
    government does not dispute that defendant met this burden of production and that the trial
    judge properly considered the necessity defense in this case. Various formulations of the
    7
    In written submissions to the district court, the defendant twice stated that the burden
    of proof was on him. Nevertheless, because the district court evidently did not hold
    defendant to this position, but instead permitted defendant later to argue that the burden
    should be on the government, and because the government does not urge on appeal that this
    issue has been waived, we conclude that the issue has been preserved.
    - 19 -
    elements of the defense may be found, but for our purposes we need only examine one such
    formulation. The necessity defense may excuse an otherwise unlawful act if the defendant
    shows that “(1) there is no legal alternative to violating the law, (2) the harm to be prevented
    is imminent, and (3) a direct, causal relationship is reasonably anticipated to exist between
    defendant’s action and the avoidance of harm.” United States v. Meraz-Valeta, 
    26 F.3d 992
    ,
    995 (10th Cir. 1994) (citing United States v. Seward, 
    687 F.2d 1270
    , 1276 (10th Cir. 1982) (en
    banc)).
    The district court’s holding that the burden of proof on the defense of necessity was
    on the defendant was expressly based on the prior ruling that the offense charged did not
    include a mens rea element. I App. at 119-20 (citing United States v. Toney, 
    27 F.3d 1245
    (7th Cir. 1994)); II App. at 687. The trial judge recognized the fundamental principle that the
    government must bear the burden of proof beyond a reasonable doubt of each element of a
    criminal offense. In re Winship, 
    397 U.S. 358
     (1970). It follows from this that when
    evidence has been produced of a defense which, if accepted by the trier of fact, would negate
    an element of the offense, the government must bear the ultimate burden of persuasion on
    that element, including disproving the defense. Mullaney v. Wilbur, 
    421 U.S. 684
     (1975).8
    8
    The Court in Mullaney unanimously held that it was a violation of the constitutional
    guarantees of due process for Maine to require a murder defendant to shoulder the burden
    of persuasion of establishing that he acted in the heat of passion on sudden provocation, so
    as to qualify for conviction of the lesser offense of manslaughter. Two terms later, the Court
    considered a New York statute which similarly placed on the defendant in homicide cases
    the burden of persuasion as to the statutory defense of “extreme emotional disturbance.”
    Patterson v. New York, 
    432 U.S. 197
     (1977). The Court upheld that statute because the
    - 20 -
    See generally 1 Wayne R. LaFave & Austin W. Scott, Jr., Substantive Criminal Law § 1.8(c)
    (1986). In the instant case, however, we do not face a constitutional issue involving
    defendant’s due process rights. The Constitution permits allocation of the burden of proof
    to the defendant with respect to a defense which does not negate an element of the crime.
    E.g., Patterson v. New York, 
    432 U.S. 197
     (1977). Therefore, because we have affirmed the
    district court’s ruling that the offense charged may be proven without proof that defendant
    intended to take his motor vehicle into the protected area, or even knew that he had done so,
    the trial judge’s ruling on the burden of proof on the necessity defense did not deny
    defendant any basic right. There still remains the question, however, whether the burden of
    proof was properly placed on defendant or whether some authority other than the
    Constitution would require the opposite conclusion. Unfortunately, neither the statutes, the
    regulations, nor the cases provide much guidance on when the burden of proof should be
    allocated to the defendant for such a defense. We must resolve the issue with the minimal
    guidance that these sources provide.
    One factor which is relied on is a practical one. Often it is the defendant who is most
    likely to have access to the facts needed to prove such a defense, and this case seems to be
    of that type. This pragmatic element is one which may properly be taken into account, as the
    crime was defined broadly as requiring only two elements – intent to cause the death of
    another and causing the death of that person or a third person. Because there was no
    requirement analogous to the common law element of malice aforethought, the defense did
    not involve negating such an element, or any element, of the crime.
    - 21 -
    Supreme Court has recognized for at least most of this century. See Morrison v. California,
    
    291 U.S. 82
    , 91 (1934). In Morrison, the Court stated that the burden of establishing an
    affirmative defense may properly be placed on the defendant if there exists “a manifest
    disparity in convenience of proof and opportunity for knowledge, as, for instance, where a
    general prohibition is applicable to every one who is unable to bring himself within the range
    of an exception.” 
    Id.
    We think it is manifest that the regulation at issue here is “a general prohibition.” It
    would be impractical, we believe, to impose on the government the burden of disproving
    necessity beyond a reasonable doubt, and this case demonstrates why this is so. It would be
    impractical to expect that the boundaries of wilderness areas could be policed in such a way
    that the government would have access to evidence to disprove a necessity defense. We
    think, in fact, that requiring the government to disprove the necessity defense could impede
    enforcement of the regulatory scheme.
    Therefore, we hold that the district judge did not err in ruling that Unser had the
    burden of proving the defense of necessity.
    We note briefly that Unser raises a sufficiency of the evidence issue as part of his
    attack on the trial court’s rulings on the necessity defense. This argument is at least partially
    premised on the contention, which we have rejected, that the burden of proof should have
    been on the government to establish beyond a reasonable doubt that Unser had already
    committed the violation by entering the wilderness area on his snowmobile before the
    - 22 -
    emergency arose. That argument of course must fail as a consequence of our rejection of its
    premise.
    Unser does also argue that the evidence was insufficient regardless of the burden of
    proof on the necessity defense. We have carefully reviewed the record and we disagree.
    Unser’s argument on this point overlooks, among other things, Agent Burd’s testimony that
    Unser’s statements only three weeks after the ordeal were inconsistent with his trial
    testimony and that Unser had said then that he did not know where he had gone only because
    he hadn’t been paying much attention, not because he was lost in a ground blizzard. Unser’s
    argument on appeal also overlooks the evidence of the location of the second machine, and
    Unser’s testimony that he had been following the windrows before the second machine
    failed. We have already noted that the trial judge specifically relied on these facts as strong
    evidence of the location of the first snowmobile. The evidence as to the location of the
    second machine was much more certain, and the windrow evidence links that more definite
    point to the location of the first machine.
    Much of Unser’s argument is devoted to recounting the inconsistencies in the other
    evidence about the location of the first machine, with particular emphasis on the district
    judge’s mistake in reading the scale of miles on the enlarged map, exhibit 3, to which we
    have previously referred.9 This part of the evidence is somewhat troublesome. Applying the
    We remind the readers that the district judge’s finding that the emergency arose about
    9
    the time that the first machine had to be abandoned is what makes the spot where that
    machine was recovered of such great importance here.
    - 23 -
    correct scale of miles, it appears that it is approximately 6.7 miles from the Red Lake Trail
    parking lot, where the ride began, to the boundary of the wilderness. As we have noted, Mr.
    Martin, on whom the trial judge relied heavily, estimated the distance at 7.2 miles, based on
    his having tried to retrace the route.
    As Unser points out, the evidence was that Gayton had driven the machine twice just
    for practice, once at Unser’s ranch and once in the area of the parking lot. Further, the
    evidence that the odometers overstate actual mileage because of slippage of the propulsion
    mechanism, evidence that Unser and Gayton had been making “play tracks” and then had
    been wandering apparently lost, and the fact that the rugged terrain would make it unlikely
    that the actual route taken would be as direct as a line drawn on a map, all are factors which,
    Unser urges, make it highly unlikely, if not impossible, that Gayton’s machine reached the
    wilderness boundary, given that its odometer showed mileage of less than nine miles.
    Although it may be that a rational fact finder could have accepted these contentions,
    we do not find the evidence so one-sided that we could hold the trial judge’s adverse findings
    to be clearly erroneous. We believe that the district judge did not err in weighing all the
    evidence and finding that Unser had not proven by a preponderance of the evidence that the
    emergency arose before he entered the wilderness area.
    V
    Finally, we consider Unser’s contentions relating to the statements he made in the
    meeting with Agents Burd and Schultz in Albuquerque. Unser makes two contentions. First,
    - 24 -
    he says that his statements should have been suppressed because he was subjected to
    custodial interrogation without having been advised of his rights under Miranda v. Arizona,
    
    384 U.S. 436
     (1966). Second, Unser contends that the statements should have been
    suppressed because they were involuntary, being the product of deception practiced on him
    by the agents. The district court rejected both contentions. The judge made a specific
    finding of fact that Unser was not in custody during the meeting, from which it followed that
    the agents were not required to advise him of his rights under Miranda. The judge also found
    that Unser was not coerced into making statements and concluded that the statements were
    voluntary.
    The Miranda issue merits little discussion. The district court’s finding that Unser was
    not in custody is reviewed only for clear error. United States v. Glover, 
    104 F.3d 1570
    , 1578
    (10th Cir. 1997). The evidence supporting the district judge’s finding that Unser was not in
    custody was essentially undisputed and was easily sufficient. The evidence was that Unser
    voluntarily appeared both on January 7 and January 8. During both days Unser frequently
    took telephone calls on his cellular phone and obviously felt free to leave the room whenever
    he wanted because he did so, going out into the hallway to talk on the telephone several
    times. There was no evidence of any coercive tactics, nor of anything coercive about the
    atmosphere of the meeting which would have led Unser to believe that he was not free to
    leave at any time. We affirm the district court’s conclusion that there was no violation of the
    requirements of Miranda.
    - 25 -
    As to the issue of voluntariness, as noted in part I-C, supra, Unser was told only that
    the agents would help him retrieve his snowmobile, even though the agents’ purpose was to
    further their criminal investigation. The trial court found that “a measure of subterfuge” had
    been employed by the agents when they induced Unser to return to the offices in
    Albuquerque for the purpose of meeting with Agents Burd and Schultz, without telling Unser
    that he was the target of a criminal investigation and instead leading him to believe that they
    were simply trying to assist him in finding his abandoned snowmobile. On the other hand,
    the judge also found that the evidence would support a reasonable inference (which he
    apparently drew) that Unser knew that he might be cited for entering a wilderness area. The
    judge referred to Unser having brought retired Agent Martinez and retired state trooper
    Valdez to the first meeting with Agent Tafoya. Also, the judge referred to testimony by
    Tafoya that at one point during his meeting with the three men, at a time when Unser himself
    might have left the room temporarily, Tafoya asked if Unser had been cited. The court found
    as a matter of fact that Unser’s statements were not coerced.
    We review the district court’s subsidiary findings of fact only for clear error, but the
    issue of voluntariness of the statements is ultimately a question of law which we review
    de novo. Glover, 
    104 F.3d at 1579-80
    . On the legal issue of whether the statements were
    voluntary, we consider the age, intelligence, and education of the defendant; the length of the
    detention (if any); the length and nature of the questioning; whether the defendant was
    advised of his constitutional rights; and whether physical coercion was employed. Glover,
    - 26 -
    
    104 F.3d at 1579
    . The inquiry is to include all the facts and circumstances. The ultimate
    
    Id.
    question in this case is whether the promise of helping Unser to locate his snowmobile
    resulted in his will being overborne. 
    Id.
    We find no clear error in the trial court’s subsidiary findings. These included findings
    that Unser was a man of intelligence and experience. As previously alluded to, the court
    found that the fact that Unser initially enlisted two men with law enforcement backgrounds
    to accompany him to meet with Tafoya suggested that Unser had some idea that he might be
    under investigation for entering the wilderness area with his snowmobile. The judge also
    found, as we read his comments, that Unser was a strong willed individual as evidenced by
    his having survived this ordeal and by other circumstances, including the fact that Unser had
    achieved great fame and success as a race car driver in his earlier years.
    Considering all the surrounding circumstances, we affirm the district judge’s holding
    that the statements were voluntarily made and therefore admissible at trial.
    VI
    For the reasons given, the judgment is AFFIRMED.
