About this map

Cortina Ridge and the Oat Hills define the complex topography of this western section of the Sacramento Valley. The landscape is etched with steep drainages including Salt Canyon, Fox Canyon, and Wilson Canyon, where various springs like Pappy Spring and Cottonwood Spring provided vital water sources in this arid environment. The northern edge of the map features the Tehama Colusa Canal, a significant piece of water infrastructure that contrasts with the natural seasonal flow of Salt Cr and Spring Cr.

Evidence of early land use is found in labels like the Schoolhouse Divide and Whiskey Hill, suggesting historical gathering points and naming conventions tied to frontier settlement. The transition from the uplifted ridges down to Becker Flat and the edges of the Central Valley illustrates the varied terrain of Colusa County, where names like Telegraph Ridge and Three Sisters served as important landmarks for those navigating the region.
