About this map

The Salinas River corridor and the surrounding canyon country define this 1947 topographic study at the border of Monterey and San Luis Obispo counties. Central to the landscape is San Miguel, where the Southern Pacific railroad follows the riverbank, and the nearby Camp Roberts Military Reservation establishes a significant federal presence, including the East Garrison and Nacimiento areas. The map details a rural geography of named canyons such as Portuguese Canyon, Vineyard Canyon, and Lowes Canyon that carve through the high ground of Middle Mountain.

Genealogists and local historians can locate smaller communities and rural landmarks like Valleton, Moca Village, and the remote Imusdale Cem. Educational life in these interior valleys is represented by the Vineyard Sch and Ellis Sch. The presence of numerous windmills throughout Indian Valley and along the various creeks like Cholame Cr illustrates the reliance on groundwater for the ranching and agricultural operations that sustained this region in the mid-20th century.
