Most visitors to City of Rocks will observe mule deer, mountain cottontail, blacktail jack rabbit,yellow-bellied marmot and golden-mantled and least chipmunks. The Reserve and surrounding area also is home to a number of species that rarely occur further north in Idaho such as piñon mouse, cliff chipmunk, ringtail, pygmy rabbit and desert bighorn sheep. Also documented within the reserve are the more elusive mountain lion, bobcat, coyote, and elk. Pronghorn antelope and bison were probably common in the area century ago, but are no longer present. All documented mammals are included in the Reserve's .
