About this map

Picacho Peak and Pebble Mountain anchor this arid landscape in Imperial County, defined by a complex network of ephemeral drainage systems. The map illustrates how seasonal water flow has carved the terrain, creating named features like Bear Canyon and a series of expansive washes including Carrizo Wash, Gatuna Wash, and White Wash.

Human presence is marked primarily by the transport corridor of Picacho Rd and Barney Oldfield Rd in the southern portion of the quadrangle. The nomenclature of the waterways, such as Burro Wash and Arrastia Wash, reflects the region's historical associations with pack animals and early mining processes. This 2012 survey provides a precise look at the landform relief and the intricate web of desert tributaries that feed into the larger Picacho Wash.
