Hoofed Animals | Ungulates
The only ungulate in the park is the mule deer, Odocoileus hemionus.
The best known members of rodentia found in the park are mice, chipmunks, squirrels, and gophers. The order also includes lesser known taxa like voles. Mice (8 species) and their allies, chipmunks (3 species), and squirrels (6 species) constitute more than half of the rodent species in the park. Most of the remaining genera are represented by only a single species like marmots, aplodontia, and porcupines. The most commonly sighted rodents are:
