Definition and stakes

Southwest Parks and Monuments Association,  Tonto Cliff Dwellings Guide: Tonto National Monument…

“ The world’s arid lands are of many kinds; here is the Upper Sonoran Desert, with its giant cactus and remarkably varied plant life. Here are found many creatures which have adapted in behavior or body features to arid conditions. Man too has evolved in the desert in many ways, over at least ten thousand years, from roving bands of primitive hunters to the massive urban developments of today.
Nearly seven hundred years ago farming Indians now called the Salado (sa-LAH-doe) fitted their lives to this desert.

“ Climate is the chief arbiter of life on earth. Each plant and animal, including man, has tolerance limits for heat and water below or above which it dies. The Sonoran desert, with its low and uncertain rainfall and high summer temperatures, thus presents one of earth’s most taxing environments. For most desert plants and animals, the main problem presented by this climatic combination is a scarcity of water. ”

“ Seriland is the most rugged portion of piedmont Sonora, and is bounded by its most forbidding desert; the territory is nearly if not quite, the most arid and inhospitable of the Sonoran province; the diurnal and sporadic temperature-ranges are apparently the widest, and the gales and other storms apparently the severest of the entire province; the flora is among the most meager and least fruitful, and the mountains are among the craggiest of the continent; the tides are among the strongest and the tidal currents among the swiftest of the world ”
