Mammals of the Southwest Mountains and Mesas

This book describes mammals of the Southwest (New Mexico, Arizona, Colorado and Utah) which live in the life zones above the low desert. There is brief discussion of mountains as wildlife reservoirs and desert "islands". The book is divided into hoofed animals, rodents, and carnivores. Includes finely executed black-and-white drawings and distribution maps.
The only point in the United States at which four states adjoin is where Utah, Colorado, Arizona, and New Mexico come together. With adjacent portions of California, Nevada, and Texas, they contain all of our Southwestern Desert. Arizona and New Mexico especially, are known as desert States and for the most part deserve that appellation. Scattered over this desert country as though carelessly strewn by some giant hand are some of the highest and most beautiful mountains in our Nation. They may occur as isolated peaks magnificent in their loneliness, or as short ranges that continue but a little way before sinking to the level of the desert. On the other hand it is in Colorado that the Rocky Mountains reach their greatest height before merging with the high country in New Mexico, and all of the States mentioned have at least one range of major size.
Two great highways cross this area from East to West. U.S. 66, “Mainstreet of America,” goes by way of Albuquerque and Flagstaff to Los Angeles; farther north U.S. 50 winds through the mountains from Pueblo to Salt Lake City and terminates at San Francisco. Significantly, they meet at St. Louis on their eastward course, and here for the moment we digress from geography to history.
