The Chocolate Mountains dominate the northern landscape of this Imperial County desert region, where the terrain transitions into a designated Aerial Gunnery Range. This military presence defines the mid-century use of the land, underscored by a network of 4WD trails and restricted zones. In the southwest, the dramatic topography of the Algodones Sand Dunes meets a more industrial landscape, marked by a Pumping Station and a prominent Pipeline corridor protected by a Dike. Extractive activity is evident throughout the southern and eastern sectors, with numerous Gravel Pit sites and a Prospect located near the mountain foothills. This map documents a specialized landscape defined by military training, resource extraction, and the infrastructure required to move water and energy across the arid basin.
