About this map

Cholame Valley serves as the central corridor of this California landscape, straddling the border where Monterey and San Luis Obispo counties meet. This modern survey illustrates a rugged ranching and drainage network defined by Cholame Cr and the heights of the Diablo Range. The terrain transitions from the high peaks in the northeast down into broad alluvial features like Turkey Flat and Stone Corral Flats, revealing how the topography dictates the sparse road network.

Water sources are vital markers in this arid environment, with several perennial points such as Willow Spring, Little Tiger Spring, and Kerr Spring noted. Toward the southwest, the Cholame Hills and Eagle Hills rise above Kerr Lake, showing the complex drainage systems of White Canyon and McMillan Canyon. The map provides a clear record of land divisions and access routes like Cholame Valley Rd that have long supported the region's agricultural character.
