sentences:  The peak was named in 1963 by members of the Mountaineering Club of Alaska because a snow patch on its north face resembles a Polar bear skin.Beginning at approximately 1000 ft., Polar Bear Peak becomes a predominantly alpine zone, characterized by exposed rock, extremely scant vegetation, a variety of lichens, and snow pack (including year-round snowfields and glaciers).Like many Alaskan mountains, Polar Bear Peak may be frequented by rock ptarmigan, Dall sheep, mountain goats, and other alpine animals.
