1951 Map of Leek Spring Hill

About this map

Eldorado National Forest defines this high-elevation landscape in the early 1950s, characterized by a series of prominent ridgelines including Mill Creek Ridge and Plummer Ridge. The drainage patterns are distinct, with the Silver Fork American River flowing through the northeast and the North Fork Cosumnes River tracing the southern bounds. Isolated settlements and points of human activity are sparse but notable, such as Morrison, Pilliken, and Plummer. High-altitude water sources like Buckskin Joe Spring, Ono Spring, and Oro Spring are scattered throughout the timbered terrain.
