2021 Map of Gallagher Flat

USGS Topo · Published 2021

About this map

The Quinn River meanders through the arid expanse of the Quinn River Valley in this corner of northern Nevada. The landscape is defined by broad alluvial basins like Gallagher Flat and the Silver State Valley, where the drainage patterns suggest a terrain of intermittent water flow and wide-open rangeland. To the south, the topography shifts abruptly as the Slumbering Hills rise above the valley floor, providing a stark geographic boundary to the surrounding flats. Early transit through this remote region is marked by Riverside Rd and River Ranch Rd, tracing the edges of the river corridor. This 2021 survey by the U.S. Geological Survey details the intersection of these traditional ranch roads with modern infrastructure, notably Route 140, reflecting the enduring reliance on the river basin for navigation and land use in Humboldt County.
