1988 Map of Little Mule Mts

About this map

The Aerial Gunnery Range dominates the southern landscape of this California desert region, marking a significant military presence within the Imperial County terrain. This 1988 survey details a stark environment defined by the jagged peaks of the Little Mule Mountains and the northern reaches of Chocolate Mountain. Between these heights, the broad Smoketree Valley provides a passage for seasonal water runoff. Drainage patterns are clearly delineated, showing how the Arroyo Seco and Milpitas Wash cut through the arid valley floor. The northern border is bounded by the Black Hills, while Blue Mtn stands as a distinct landmark to the south, illustrating the complex topographical shifts across the military-managed lands of the late twentieth century.
