USGS Topo · Published 1948

About this map

The Mt Wilson Observatory crowns the peaks of the San Gabriel Mountains in this survey based on fieldwork from the early 1930s. The landscape is defined by the high-elevation crests of San Gabriel Peak, Mt Harvard, and Mt Markham, where a network of firebreaks and the Vetter Mtn Lookout emphasize the vital fire suppression infrastructure within the Angeles National Forest.
