About this map

The Naval Auxiliary Air Station stands as a prominent mid-century installation at the base of the Diablo Range, where the flatlands of the San Joaquin Valley meet the rising terrain. This survey reveals a landscape defined by significant water engineering projects, including the Hetch Hetchy Aqueduct and the Delta-Mendota Canal, which traverse the boundary between San Joaquin and Stanislaus counties. The small settlement of Solyo is positioned along the Southern Pacific railroad line, serving as a focal point for the surrounding agricultural and ranching operations.

To the west, the elevation climbs toward Mt Oso, cut by numerous drainages like Ingram Canyon and Hospital Creek. Local history is preserved through markers such as the Rising Sun School and named landmarks like Chicken Flat. The presence of a Prospect and various reservoirs suggests the varied land use of the era, from ranching in the canyons to strategic military aviation and large-scale water transport across the valley floor.
