USGS Topo · Published 1956About this map
Settlements like Loma Rica and the now-obscure Iowa City anchor this 1940s landscape, where small-scale agriculture and early mining enterprises defined the local economy. The terrain is marked by an intricate network of irrigation and mining canals, including the Browns Valley Ditch, Mahle Ditch, and Olive Ditch, which redirect water across the slopes of Browns Valley Ridge. These waterworks reflect the region's transition from gold-era infrastructure to supporting local orchards and ranches.
