1951 Map of Leek Spring Hill

About this map

Eldorado National Forest dominates this 1951 study of the high timber country along the boundary of El Dorado and Amador Counties. The landscape is defined by the steep canyons of the North Fork, Middle Fork, and South Fork Cosumnes River, where narrow ridges like Baltic Ridge and Plummer Ridge separate the watercourses. This era shows an active industrial landscape before the full shift to modern recreation; the map identifies numerous historical resource extraction points such as the Arbor Mine, Spread Eagle Mine, and the sites of the Girard Mill and Tuman Mill.
