Because the lower Precambrian rocks through the Upper Granite Gorge are resistant to erosion, steep walls and a narrow V-shaped canyon are produced. The great length of the rapids and the thunder produced by the sound of the waves reverberating from the walls as the water tumbles through the gorge, gives the rapids a frightening aspect. There is little substrate [...]

There is little substrate for terrestrial plants near the river or above on the cliff facees. (Altitude 770 meters). Grand Canyon National Park. Coconino County, Arizona. August 29, 1872.
