About this map

Cleveland National Forest dominates the rugged landscape of this San Diego County quadrangle, where the steep peaks of El Cajon Mtn and the Silverdome overlook the massive reservoir of El Capitan Lake. The 2021 survey shows a complex interface of protected wilderness and developed valleys. Along the western edge, the settlement of Barona sits within the Barona Valley, connected to the high plateau of Barona Mesa by a network of local roads and trails like the Garnet Mine Trl.

The hydrology of the region is defined by the San Diego River, which flows into the south end of the lake, joined by numerous drainages including Conejos Cr and Sands Cr. To the north, the San Vicente Valley and Windmill Flat offer a distinct topographical character compared to the high ridgelines of San Vicente Mtn and Rock Mtn. This map serves as a precise modern record of the canyons and peaks that separate the inland valleys from the reservoir basins.
