Headwaters. Cascade Falls. The “mouth” of the Virgin River. Utah.
The Virgin River is responsible for the creation of Zion Canyon. It is a short river, with an incredible gradient of around 70 feet per mile in the main canyon. Its source is Navajo Lake on Cedar Mountain. Owing to the limestone under the lake, many springs feed into the river, the main one at Cascade Falls with the drainage leading to Zion and West Temple on the horizon.
