Arctic Ground Squirrel

Arctic Ground Squirrel, Spermophilus parryii

The Arctic ground squirrel is adapted to live in the extreme cold of arctic environments, but its burrowing nature restricts it to areas where permafrost occurs more than a meter below the surface. Currently, this animal is found in Alaska, northern British Columbia, and the Yukon and Northwest Territories, where it is known alternatively as a gopher or sik-sik. Its recovery from late Pleistocene sites in the central U.S. indicates that this region experienced much cooler temperatures during that time period.
