About this map

The Navajo Indian Reservation dominates this mid-century landscape, where the high desert plateau meets the dramatic descent into Marble Canyon. Along the western edge, the Colorado River carves through the rock, marked by treacherous stretches like House Rock Rapids and Sheer Wall Rapids. The terrain is defined by the massive verticality of the Echo Cliffs, which separate the Little Valley from the expansive Tanner Wash drainage system.

Evidence of human adaptation to this arid environment appears at Tanner Well and the remote Canyon Utah Flat. Water management is central to the area's geography, with isolated landmarks such as Bitter Spring, Red Mesa Reservoir, and the Limestone Tanks providing vital resources across the Gray Grass Bench. Transport is limited to a network of foot trails and jeep trails navigating through gaps like Antelope Pass.
