Alien life?

Mammal? Ursine, bearlike, white faced, snowy coat. Is there an abominable snowman? An alien creature or a hidden anthopoid ancestor? Related to the mythical Big foot? Could something survive in hidden valleys up in the mountains? Living in caves. Quiet and intelligent. Their furry bodies insulated against the cold. Would melting glaciers and snow force them higher and higher? Their camouflaged bodies keeping them hidden from the increasing population of mountaineers and walkers encroaching on their space.

A digital drawing of an imagined creature. Making up a history and biology of it is interesting but I don’t have the skills to really write it.
