1958 Map of Crystal Lake

About this map

Crystal Lake Recreation Area serves as the focal point for this high-altitude landscape in the Angeles National Forest. Mapped during the late 1950s, the terrain is defined by the steep ridges and peaks of the San Gabriel Mountains, including Mt Baden-Powell and Mt Islip. The map documents a developed recreational infrastructure from the mid-century era, featuring the Crystal Lake Guard Sta. and an Outdoor Theater near the lake. The Angelles Crest Highway winds across the northern ridges, passing through Islip Saddle and Dawson Saddle, providing access to numerous springs and designated camps like Little Jimmy Campground. The hydrology is equally detailed, tracing the headwaters of the North Fork San Gabriel River and the South Fork Big Rock Creek, alongside smaller landmarks like Falling Springs and Mine Gulch, which suggest the area's geological and prospecting history.
