USGS Topo · Published 1939About this map
Mt Wilson Observatory stands as the focal point of this 1930s topographic study, perched above a network of canyons and peaks within the Angeles National Forest. The map documents a significant era of recreational and administrative development in the San Gabriel Mountains, characterized by numerous wilderness camps and lodges. These early mountain retreats, including Opids Camp, Sturtevant Camp, and Valley Forge Lodge, were linked by rugged trails and the emerging Angeles Crest Highway, representing a period when the range was becoming increasingly accessible for scientific research and forest management.
