Cover: The watersheds of Arizona appear on this digital map created by Ray Sterner of Johns Hopkins University's Applied Physics Laboratory. The image, with north at the top, shows an area about 200 by 150 miles, with the Colorado River and the Grand Canyon at the top. The Colorado Plateau occupies the top and upper right portions of the view, with the Basin and Range terrain visible in the lower left. Between the two is a northwest-southeast trending transition zone of mountainous terrain. The oblong blue feature in the lower center of the image is Roosevelt Lake, impounded by Theodore Roosevelt Dam. This image, and similar ones for all states, is available on the World Wide Web at http://fermi.jhupal.edu/states/states.html.
