A Field Guide to Desert Holes

They're everywhere in the desert! Ground holes. Elevated holes. Divots. Mounds. The revised edition of this quirky and popular field guide helps curious visitors -- as well as seasoned naturalists -- sort through the often bewildering abundance of desert holes so they can find out who's behind all that digging. Includes over 60 drawings of desert animals, their holes, and their tracks, and over 50 full-color photographs.
