(CNN) A Utah man has been rescued from the Alaskan wilderness, approximately three weeks after a fire burned his home to the ground, killed his dog and left him without much food, clothing or shelter.

Tyson Steele, 30, was found among the rubble of his remote homestead in the Susitna Valley on Thursday morning, according to a news release from the Alaska State Troopers, after friends asked authorities to perform a welfare check after not hearing from him.

In aerial footage shared by the troopers, Tyson steps out among the snow-covered remains of his home, waving to the troopers in a helicopter, a large "SOS" carved out of the snow behind him.

"Everything that I owned was consolidated in that cabin," Steele told troopers, who shared Steele's survival account in the detailed release

In the weeks after the fire, Steele said, he survived on the remnants of canned rations and peanut butter, sleeping in a snow cave and makeshift shelter that he built around his wood stove.
