The San Andreas Fault cuts a significant geological path through this portion of the Angeles National Forest, defining the steep drainages and ridge lines of the Sierra Pelona Mountains. Near the settlement of Three Points, the terrain is marked by deep incisions such as Redrock Canyon and Kimbrough Canyon, where water management infrastructure like the Los Angeles Aqueduct navigates the complex topography. The map illustrates a landscape where recreational and utility corridors intersect, with the Pacific Crest National Scenic Trail winding across high points like Liebre Mtn and Sawmill Mtn. Small upland water bodies including Tweedy Lake and Hidden Lake provide rare riparian points within the high-elevation canyons. This modern survey reflects the continued balance of protected forest land and critical regional water infrastructure in northern Los Angeles County.
