LANDER, Wyo. (AP) — Authorities say a man who spent the night stranded on the Continental Divide Trail in blizzard conditions had been snowmobiling with a commercial guide service that did not notice he was missing until the group reached its destination.

Capt. Ryan Lee with the Fremont County Sheriff's Department said Monday the trip originated in Sublette County and reached its destination in Fremont County the evening of Jan. 18.

The 57-year-old Minnesota man was found alive the morning of Jan. 19, with his snowmobile, after spending the night in the Union Pass area in western Wyoming. He seemed to be suffering from exposure and possible hypothermia, but his condition has not been released.

The Casper Star-Tribune ( ) reports Lee declined to release the names of the guide service or the snowmobiler.
