The search may be called off for a Colorado man on Monday.
52-year-old Dale Brownlow of Denver hasn't been seen since Dec. 1.
His car was found at a trail head in Helena National Forest in Montana. Snow and freezing temperatures have come and gone in that area since he was last seen.
Brownlow is a wildlife biologist known to spend long periods of time camping, so the search didn't start until last week.
Lewis and Clark County officials in Montana said that if they didn't find any clues to his whereabouts by Sunday, the search would be called off.
