About this map

Lake Davis dominates the eastern half of this terrain, a reservoir with an elevation of 5775 feet that reshaped the local topography. Bordered by the Plumas National Forest, the map records specific historical locations such as the Midway House (Site) and Gate Place (Site) in Grizzly Valley, providing precise markers for local historians and genealogists tracking early Sierra Nevada activity.

The high-elevation landscape is defined by massive ridges, including Turner Ridge and Grizzly Ridge, which rise toward Mt Ingalls. In the southern reaches, State Game Refuge 1-V occupies the drainage around Threemile Creek and Dan Blough Creek. Remote camps and seasonal locations like Sheep Camp in Happy Valley suggest a history of grazing and forest management within these Plumas County highlands.
