1944 Map of Morgan Valley

USGS Topo · Published 1944

About this map

Reid Mine, Harrison Mine, and the Manhattan Mine anchor an active mining landscape along the borders of Lake, Colusa, and Napa counties during the early 1940s. Centered on the settlement of Knoxville, this area shows a distinct pattern of isolated ranching and resource extraction. The presence of the Morgan Valley Sch near Grizzly Pk indicates a established community presence in the valley, while named holdings like Hennesey Ranch and Ink Ranch reflect the private land use of the era. The terrain is defined by the significant drainage of Cache Creek and Putah Creek, with many smaller seasonal tributaries such as Butcherknife Creek and Jerusalem Creek carving through the high ridges. These water sources and family-named landmarks provide a detailed look at the rural northern California interior before mid-century development altered many such remote outposts.
