1987 Map of Chalfant Valley

About this map

The Chalfant Valley settlement occupies a narrow corridor of development between the towering White Mts and the desert floor in the late 1980s. This landscape is defined by its industrial and hydraulic infrastructure, featuring an extensive Aqueduct and a Powerhouse that reflect the region's historical role in water and power management. Evidence of mineral exploration is scattered across the alluvial fans and canyon mouths, with numerous sites such as the Jeffrey Mine, the Copper Queen Mine, and the Sacramento Mine marking the rugged slopes. Within the Inyo National Forest, the terrain is deeply incised by drainages like Jeffrey Canyon and Sabies Canyon, while high-altitude features like Moulés Mine suggest the difficult reach of early 20th-century prospecting. The presence of a Radio Facility and multiple Prospect sites indicates a mix of modern communication needs and enduring geological interest in the high desert.
