About this map

Mono Basin and the eastern slopes of the high Sierra are documented here just before the mid-century, showing a landscape defined by isolated ranching outposts and early timber operations. The northern reach is anchored by the Mono Mills site near the shores of Mono Lake, while the expansive Adobe Valley contains several established homesteads including the Adobe Ranch and River Spring Ranch. These settlements were critical nodes in an arid high-desert environment, often situated near vital water sources like River Spring and Cowtrack Spring.

To the south, the transition into the Inyo National Forest reveals early recreational and mining footprints. The presence of McGee Creek Resort and Toms Place signals the area's growing importance for travelers, even as industrial sites like the Casa Diablo Mine and thermal features like Casa Diablo Hot Springs remain prominent. The survey also captures the original route of the Mt Diablo Base Line, crossing through the Benton Range toward the settlement of Benton.
