The South Fork Trinity River carves through this northern California landscape, forming the boundary between the Trinity National Forest and Six Rivers National Forest. This modern survey records the complex system of forest routes and ridge-top lookouts used for land management, such as Horse Ridge Lookout Rd and Bramlet Rd. Named grazing lands and water sources like Red Mountain Pasture, Swim Meadow, and Seven Up Cedars Spring speak to the area's legacy of high-country ranching and resource use. The topography is defined by high points like Red Mtn and South Fork Mtn, separated by deep drainages including Murphy Gulch and Dog Gulch. This map provides a detailed view of the watershed before it joins the larger Trinity river system, documenting a region dominated by timber and wilderness management.
