1994 Map of Hammil Valley

About this map

Blind Spring Hill and the Volcanic Tableland dominate this high-desert landscape in Mono County, where the desert floor meets the rising slopes of the Inyo National Forest. This 1994 revision, based on imagery dating back to 1954, documents a region defined by extraction and resource management. Numerous Open Pit Mines and scattered prospects are mapped across the western ridges, including the Silver Reef Mine near Yellowjacket Canyon. The settlement of Hammil (Site) is recorded as a former location on the valley floor, adjacent to a utility corridor and a local Landing Strip. Water resources are central to the map's details, showing a network of aqueducts and wells supporting agricultural activity like feedlots and the ecologically sensitive Fish Slough, which is designated here as part of an Environmental Area of Critical Concern.
