No, it's not that Grand Canyon, but the canyon carved by the Yellowstone River is indeed called the Grand Canyon of the Yellowstone and is quite impressive in its own right. Most people just view the canyon and falls from the rim, but to get a better look at it (and the Lower Falls) we took a somewhat arduous hike down what is called Uncle Tom's Trail. It's a trail at the start, anyway; most of it consists of a set of metal staircases and platforms drilled right into the wall of the canyon. These vibrate when people walk on them (not good for photographers) and they feel very open and exposed (not good for acrophobics). I, of course, am an acrophobic photographer, but the photography takes precedence so I set my fears aside and forged onward. :)

This image was taken looking downstream from Yellowstone Lower Falls, and shows a typical view of the majestic Yellowstone Canyon, inclduing yellowish color of the walls, which gives the River its name (as well as the Canyon, and the Park!)
