About this map

Sugarloaf Mountain anchors this high-altitude landscape where residential growth meets protected wilderness in the San Bernardino National Forest. The map documents a distinct concentration of institutional retreats and summer camps, such as Promised Land Camp, University Camp, and Camp Akela, clustered around the headwaters of the Santa Ana River. At the base of the peak, the community of Sugarloaf and the developing Woodlands neighborhood show the expansion of permanent settlement into Bear Valley.

Transitioning from recreational areas like the Gold Mine Ski Area to the remote San Gorgonio Wilderness, the topography reveals a landscape shaped by seasonal water and winter sports. High-country landmarks such as Poopout Hill and the seasonal Erwin Lake define the terrain, while Barton Flats serves as a hub for campers and travelers. This 1988 update reflects the intensification of the suburban-wildland interface, particularly visible in the street grids of Moonridge.
