USGS Topo · Published 2021About this map
The Middle Fork Mokelumne River and the S Fork Mokelumne River converge along the northern edge of this terrain, where the Calaveras and Amador county lines meet. The landscape is defined by its deep drainages, including Valentine Gulch and Humbug Gulch, which feed into the larger river systems. Historically significant routes like the Old Emigrant Trail cross the southeastern reaches, hinting at the area's role in early California migration.
