1940 Map of Rock Creek

USGS Topo · Published 1955

About this map

The Andreas Rift Zone cuts a distinct geological path across this landscape, separating the high peaks of the Angeles National Forest from the high desert fringe. In the north, early settlements and landmarks like Pearblossom, Llano, and Saunders Ranch sit along the transition to the Antelope Valley. The historic Fort Tejon Road skirts the base of the Holcomb Ridge, reflecting the early transportation corridors used before modern highways. Deep in the canyon country, Valyermo and Shoemaker mark small outposts near the path of Big Rock Creek. The southern portion is dominated by the steep terrain of the San Gabriel Mountains, where the winding Angeles Crest Highway provides access to summits like Mt Islip and the recreation hub at the Crystal Lake Guard Sta.
