Joshua Tree National Park encompasses the northern half of this desert landscape, where the Eagle Mountains rise sharply above the basin floor. A vital piece of California water infrastructure, the Colorado River Aqueduct, traverses the center of the sheet, entering the West Eagle Mountain Tunnel as it heads toward the coast. The southern reaches of the map are defined by the ephemeral Hayfield Lake and the wide alluvial plains of Red Cloud Wash. This area represents a critical intersection of natural wilderness and the engineered systems required to sustain regional development. Geographic landmarks like Hayfield Spring and Hayfield Summit Spring indicate the locations of precious water sources in an otherwise arid environment, while the steep grades of Difficult Canyon and Boulder Canyon showcase the complex drainage patterns of the Colorado Desert.
