1955 Map of Gilroy Hot Springs

USGS Topo · Published 1957

About this map

Gilroy Hot Springs and the surrounding Diablo Range backcountry are documented here during the mid-1950s, a period defined by rugged land use and early water management. The area is dominated by significant ridgelines like Palassou Ridge and Phegley Ridge, with the drainage of Coyote Creek cutting through the center of the sheet. Evidence of ranching and early development appears in labels for the Wilson Ranch and Center Flats, while the presence of a Pipeline and multiple reservoirs, including the Braen Reservoir, highlights the region's importance for water infrastructure. The southern portion of the map transitions into the broader valleys of Llano Del Tequisquita and San Ysidro Valley, providing a clear look at how the mountain terrain meets the agricultural flats of Santa Clara County.
