1956 Map of Sonora Pass

USGS Topo · Published 1959

About this map

The High Sierra crossing at Sonora Pass serves as the focal point for this 1956 topographic study, marking the high-altitude boundary where Stanislaus National Forest meets the Toiyabe National Forest. The landscape is defined by its seasonal use and military footprint, notably featuring the Marine Corps Cold Weather Camp near the Pickel River and the Millie Lake Campground. Genealogists and local historians can locate the historic Leavitt Sta (Site) on the eastern slopes, a remnant of early travel through these mountains.
