Description :
The AA. calculate episodic incision rates of the Colorado River based on absolute ages of 2 levels of Quaternary deposits adjacent to Glen Canyon, along the north flank of Navajo Mountain. Minimum surface ages are determined by a combination of cosmogenic radionuclide surface exposure ages, uranium series and soil-development formation times. The AA. also determine incision rates of 2 tributaries to the Colorado River : Oak Creek and Bridge Creek.
