1985 Map of Bitter Springs

About this map

Marble Canyon serves as the dramatic centerpiece of this 1985 provisional study, where the Colorado River carves through the landscape between the eastern edge of Grand Canyon National Park and the western reaches of the Navajo Indian Reservation. The river's path is marked by a series of significant whitewater features including Soap Creek Rapids, Sheet Well Rapids, and House Rock Rapids, providing a clear look at the hydraulic character of the canyon floor before modern river management shifts.
