2018 Map of Mammoth Wash

About this map

The Chocolate Mountains dominate this arid landscape in Imperial County, where steep-walled drainage systems define the movement of water and terrain. The vast network of Mammoth Wash snakes through the central and western sections of the quadrangle, joined by the smaller German Diggins Wash to the north. This 2018 topographic study highlights the isolation of the range, showing an environment shaped by episodic desert flow and sharp elevation changes. To the northwest, Martinez Gulch provides a distinct break in the landforms near the boundary of the township and range survey lines. The lack of modern structures or permanent roads underscores the area's character as a preserved wilderness of the Colorado Desert, where land remains largely managed under federal jurisdiction through the Bureau of Land Management.
