1962 Map of Penon Blanco Peak

USGS Topo · Published 1987

About this map

The rugged boundary between Tuolumne and Mariposa Counties is defined here by the high elevation of Peñon Blanco Ridge and the deep cuts of the Tuolumne River drainage. At the time of this 1962 field check, the landscape is a patchwork of early mining claims and small cattle-country settlements. Significant mining heritage is visible through labels for the Buzzard Roost Mine, Salambo Mine, and the White Rock Mine near the county line.
