The forest provides many learning opportunities, and as such may be seen as the ultimate 'learning center'. Education can be gleaned from the diversity of rugged mountains, deep canyons, meadows, and semi-desert country. Elevations range from 4,200 to 10,900 feet and cover four of the six life zones. Flora and fauna are diverse. Ocotillo and cactus are found in the lower elevations, and juniper, pine, aspen, and spruce-fir forests are plentiful in the high mountains. Wildlife such as the black bear, mountain lion, elk, deer, antelope, bighorn sheep, and wild turkey inhabit the Forest while the bald eagle, peregrine falcon, and the red-tailed hawk soar in the wind. A popular activity for many forest visitors is attending interpretive programs offered by forest specialists.
