His family said he had outdoor experience.
One would think he would have had extra clothing and/or long underwear in his luggage to bundle up in before leaving out on his own. Blue jeans alone will not suffice in those temperatures and snow.
Cotton jeans are terrible in cold and cool weather.
If cotton gets wet and cold...very bad.
Apparently he had no hat; he would lose alot of body warmth thru his uncovered head.
a hunter with vast experience got lost in north eastern Washington two months ago....he wandered and wandered and finally they found him 19 miles from his camp...he simply sat down under a tree and went to sleep permanently.....
