1938 Map of Mt. Boardman

USGS Topo · Published 1957

About this map

The Diablo Range landscape in 1938 was a complex terrain of remote ranching and industrial outposts. This survey, prepared under the direction of the Chief of Engineers, reveals a region defined by family holdings such as the Livermore Ranch and Banta Ranch. The remote San Antonio Valley serves as a central hub for the area, featuring the San Antonio Valley Sch and providing a rare pocket of level ground between the peaks of Mt Boardman and Mt Stakes.
