1956 Map of San Ardo

Remote valleys like Peachtree Valley and Pancho Rico Valley are shown with their complex networks of gulches and canyons, including Jim Lawson Gulch and Dutch Henry Gulch. Small stops and geographical markers such as Docas, Lorenzo, and a Cemetery south of Long Valley provide critical points of reference for genealogists tracking local families. The presence of the Airline Highway in the north suggests the era's evolving transportation patterns across the California Coast Ranges.
