Yes Bigguy it can very easily happen especially while tracking an animal . It can get really bad if the snow sticks to the trees . Fortunately he still had a half a day of daylight left and could backtrack himself in the fresh snow too .
Definitely have to remain calm which can be hard to do for many .
My bro-inlaw belongs on the ERT team here and they get called for many searches for lost moose hunters especially . Most hunters are usually prepared though and when found they are usually in pretty good shape or find their own way out . Good story .
