The Rock Squirrel is a large, mottled ground squirrel of rocky desert canyons and cliff faces in the American Southwest. It is the largest ground squirrel in the United States and is closely associated with rocky substrates, climbing boulders and cliff faces with surprising agility. Rock squirrels can carry rabies and have bitten visitors at national parks who attempt to feed them—it is among the wildlife most involved in human bite incidents in the Southwest.
