The Colorado River has carved many canyons along its course, a distance of over 1,400 miles from its headwaters in the Colorado Rockies to its mouth at the Gulf of California. Its Grand Canyon stretches for 277 miles in northern Arizona. Much of the geologic history of the North American continent is revealed in the walls of Grand Canyon and in the high plateaus to its north in what has come to be known as the Grand Staircase. There are deeper canyons and wider river valleys, but nowhere has the combination of bedrock, climate, geologic structure, and history conspired to produce anything quite like Grand Canyon.
