The southern reaches of the Chocolate Mountains dominate this arid landscape in Imperial County, where the desert floor is carved by seasonal drainages and ancient water sources. The Pegleg Well provides a critical anchor point in this remote terrain, situated near the head of German Diggins Wash. The map details a complex network of topographical features, including the stark relief of Martinez Gulch and the winding course of the Arroyo Seco to the north. This 2015 survey reflects the enduring character of the Colorado Desert, documented through modern digital cartography yet preserving the names of the isolated landmarks that have guided travelers through these southeastern California reaches for generations.
