2012 Map of Diamond Mountain

About this map

The Peter Lassen Grave stands as a significant historical marker on this map, located just south of Richmond Ridge and Emerson Lake. This high-altitude terrain in Northern California is defined by the massive profile of Diamond Mountain, which anchors a landscape of high basins and seasonal water sources. The map traces a complex network of forest access routes, including the Diamond Mountain Mtwy and Pierce Creek Mtwy, which navigate the steep drainage systems of Hills Cr and Indian Cr. Land use in the early 21st century is reflected in features like the Wheeler Sheep Campground, while the presence of the Emerson Ditch indicates the ongoing management of water resources in this arid upland environment. Diverse terrain features such as Gilman Basin and Aspen Flat break the forested slopes, providing localized landmarks for those studying the geography south of the Susanville area.
