About this map

Grass Valley serves as a central agricultural corridor in this high-altitude landscape, where the settlement of Greenwich sits near the base of Monroe Mountain. The 2020 geography highlights a complex irrigation and water management system essential for mountain ranching, featuring the Koosharem Canal and the Otter Cr drainage. Significant water storage is provided by the Upper Box Cr Reservoir and Lower Box Cr Reservoir within the bounds of the Fishlake National Forest.

Canyons such as Browns Canyon, Shaffers Canyon, and Jackie Canyon cut through the western slopes, while the eastern edge is defined by the rise of Parker Mtn. Local infrastructure is marked by a network of forest trails and rural routes, including the S Old Red Schoolhouse Rd and Magleby Ranch Rd, reflecting the area's long-standing ranching heritage and the importance of sites like Little Meadow for summer grazing.
