Scorpions and Gila monsters, jackrabbits and coyotes, bats, butterflies and 14 varieties of hummingbirds are just a few examples of the diverse wildlife population of Arizona. While 25 percent of Arizona is blanketed by lush forests, it is also the only state where four deserts are found. Its varied terrain includes vast plateaus, deep caves and caverns, steep canyons and lofty mountains -- even volcanoes. Desert Digits guides children through the wonders of Arizona, where they can pan for gold, shoot the rapids on the Colorado River and camp in the Grand Canyon. They will also learn about Native American art and traditions, how to avoid a scorpion sting, how tall cacti grow, and the right way to make and eat a tortilla.
