2021 Map of Castle Dome

About this map

Clipper Mountains dominate the northern terrain of this San Bernardino County landscape, rising sharply above the southern expanse of the Mojave Desert. The eponymous Castle Dome stands as a prominent landmark in the northeast corner, overlooking a network of utility and transport routes that traverse the desert floor. Water is a scarce and vital element here, represented by the isolated Bonanza Spring located at the mountain's edge. Below the high peaks, the Fenner Valley opens into a broad alluvial plain, where long-distance tracks like the Ns203: Needles To Ludlow Truck Trl and the 100 Trl reflect the historical and modern reliance on established desert crossings. This survey captures a rugged corner of California where the transition from high peaks to flat desert basins dictates the path of every trail and the location of every rare water source.
