2021 Map of Crystal Lake

About this map

Angeles National Forest dominates this high-elevation segment of the San Gabriel Mountains, where the 2021 topography details the steep relief surrounding the iconic Crystal Lake. The map reveals a complex network of recreation infrastructure, including the Pacific Crest National Scenic Tri as it traverses major peaks like Mt Baden-Powell and Mt Burnham. Local history and recreational development are evident at the Pine Flats area, which features the Pine Flats Amphitheater and West Pine Flat grounds. This modern survey tracks the intricate hydrography of the region, from the headwaters of the N Fork San Gabriel River to high-altitude water sources such as Little Jimmy Spring and White Fir Spring. The presence of Mine Gulch near Vincent Gap serves as a spatial reference to the area's earlier resource extraction history, now largely transitioned to wilderness and managed recreation.
