About this map

Lassen National Forest terrain dominates this 1991 provisional survey, which highlights the complex drainage systems and high-altitude landmarks of Tehama County. The landscape is centered on the prominent Colby Mountain and the high point of Onion Summit, with the Colby Lookout Tower providing a strategic vantage point for fire management. The map details a dense network of watercourses, including the steep descents of Deer Creek and Mill Creek, where vertical drops are marked by Deer Creek Falls and Lower Deer Creek Falls.

Recreational and conservation uses are evident through the Potato Patch Campground and Deer Creek Campground, alongside the extensive boundaries of the State Game Refuge 1-G. Local history and geography are preserved through family-named or descriptive landmarks like Onion Butte and Rattlesnake Creek, offering a precise record of the backcountry before modern development or shifting forest management practices altered these wilderness access points.
