2023 Map of Grass Valley

About this map

Grass Valley serves as the primary hub in this Sherman County landscape, where the high plateau is deeply incised by a complex system of drainages. The topography is defined by the sharp descent into Allison Canyon and Mack's Canyon to the northwest, while the township itself sits on relatively level ground flanked by Grass Valley Canyon. This rural landscape is marked by long-established section lines and roads such as Twin Lakes Rd and Finnegan Rd, tracing the routes between early homesteads and agricultural centers.
