About this map

The Madeline Plains anchor this high-elevation landscape in Lassen County, where the transition from flat basins to corrugated ridges defines the local topography. This region is characterized by a sophisticated system of water management, evidenced by numerous named catchments such as Bailey Reservoir, Elmers Reservoir, and Pinecone Reservoir. These features, alongside Chase Spring, suggest the critical importance of water rights and livestock management in this arid stretch of Northern California.

Tracing the historical human footprint reveals the Dry Valley Cemetery tucked into the northwestern hills, a silent waypoint for genealogists researching early settlement families. Navigation through the complex terrain follows established routes like the Termo Grasshopper Rd and CR-513, which cross through topographic features like Whiskey Canyon and the broad expanses of McCoy Flat and Cleghorn Flat. The map provides a precise view of the Public Land Survey System township and range boundaries, which remain foundational to land ownership in this part of the state.
