2021 Map of Mesa Grande

About this map

Mesa Grande sits at the heart of this San Diego County upland, where ranching heritage meets the protected lands of the Cleveland National Forest. The landscape is defined by a series of dramatic geographic depressions and rises, including Pamo Valley and Long Valley, separated by prominent features like Mid Ridge and Black Butte. Water is a central element of the terrain, with the San Luis Rey River flowing into the northern reaches near Lake Henshaw. Smaller drainages such as Black Canyon Cr and Temescal Cr carve through the canyons, while Washtub Falls and Black Mountain Spring provide specific points of interest for those studying the hydrology of the region. The map documents an area where remote ranching operations like Loma Madera Ranch/Airport are accessed by winding routes such as Mesa Grande Rd and Guejito Truck Trl.
