About this map

The San Jacinto Mountains dominate this landscape, showcasing a high-altitude wilderness managed by the San Bernardino National Forest and including a portion of the Santa Rosa Indian Reservation. Miners and prospectors were active along the upper slopes of Thomas Mountain and Gold Hill, leaving behind traces such as the New Hemet Bell Mine and the Gold Shot Mine. The Pacific Crest National Scenic Trail traverses the rugged ridges, connecting high points like Butterfly Peak and Lookout Mountain with the more level terrain of Vandeventer Flat.

Water sources are vital markers on this arid terrain, with numerous named springs and tanks supporting both local transit and ranching operations. Features such as Kenworthy Station and the solitary Cem near the reservation boundary reflect the long-standing human presence in these high valleys. The transition from the steep canyon walls of Palm Canyon to the broad Terwilliger Valley illustrates the complex topography of the southern California backcountry during the early 1980s.
