Centered on the Sacramento Valley, this colorful map presents a huge amount of information in the region from Chico south to Vallejo.

The legend uses icons to indicate twenty-seven physical features, topography and more. Surveyed by L.C. Holmes, Department of Agriculture and J.W. Nelson, University of California.
