1949 Map of Duckwall Mtn

About this map

The Clavey River carves a deep path through the center of this terrain, meeting the Tuolumne River at the southern boundary. This 1949 survey illustrates the mid-century footprint of the timber industry, notably the Lumber R. R. winding along the eastern ridges near Camp 45. The land is defined by prominent high points like Duckwall Mtn and Thompson Peak, which overlook a network of seasonal drainages and meadows. Small-scale human presence is marked by isolated landmarks such as Quinn Ranch and Walton Cabin Spr. The survey also delineates the Mt Diablo Base Line, a critical surveying reference, and notes the presence of a Lookout on Duckwall Mtn, reflecting the area's integration into the Stanislaus National Forest management system.
