Fodor's Expert Review Chasm and Painted Wall Views
At the heart-in-your-throat Chasm viewpoint, the canyon walls plummet 1,820 feet to the river, but are only 1,100 feet apart at the top. As you peer down into the depths, keep in mind that this section is where the Gunnison River descends at its steepest rate, dropping 240 feet within the span of a mile. A few hundred yards farther is the best place from which to see Painted Wall, Colorado's tallest cliff. Pinkish swaths of pegmatite (a crystalline, granitelike rock) give the wall its colorful, marbled appearance.
