Mendocino National Forest terrain dominates this 1990s-era survey of Glenn County, revealing the intricate drainage patterns and remote access points of the Coast Ranges. The topography centers on the small settlement of Alder Junction, a focal point for the mountain roads that thread through this high-elevation landscape. Water resources are mapped in detail, including the steep descent of Browns Canyon and the headwaters of Watson Creek, which define the local watershed. The map serves as a precise record of forest service infrastructure and land management boundaries during a period of transition in California's northern timber and recreation lands. It highlights the stark contrast between protected national forest land and the occasional private inholdings that persist in these isolated canyons.
