2021 Map of Grasshopper Valley

About this map

Grasshopper Valley dominates this high-altitude landscape in Lassen County, where seasonal hydrology and remote ranching infrastructure define the terrain. The valley floor is flanked by the prominent Grasshopper Ridge to the east and the Bald Hills to the southwest, creating a classic Great Basin basin-and-range profile. Water management is central to the area's utility, evidenced by the presence of the Saddle Horse Flat Reservoir and Tom Spring Reservoir, along with numerous isolated water sources like York Springs and Luddy Spring. In the northeast corner, Dry Valley and the Dry Valley Ridge show the transition toward Dry Valley Gap. The network of unpaved roads, including Termo Grasshopper Rd and S Grasshopper Rd, reveals the enduring reliance on these corridors for accessing livestock ranges and remote mountain tracts.
