1978 Map of Three Rivers

About this map

The Great Western Divide anchors this high-elevation landscape, separating the drainage systems of the Kern River and Kaweah River. This 1978 survey highlights the complex land management of the southern Sierra, where Sequoia National Park meets the Sequoia National Forest and the Tule River Indian Reservation. In the west, the valley floor shows the growth of Porterville and the development of Lake Success, while high-country settlements like Silver City and Camp Nelson provide windows into the region's recreation and timber history.
