2018 Map of Janesville

About this map

Janesville sits at the foot of the Diamond Mountains in the Honey Lake Valley, serving as a focal point where the forest meets the basin. This 2018 survey documents the interface between the Lassen National Forest and the northern reaches of the Plumas National Forest. The landscape is defined by its water management and dramatic elevation changes, from the high Thompson Peak down to the Lake Leavitt Inlet Canal and the waters of Lake Leavitt. Local history is anchored by the Janesville Cem and Diamond Crest Cem, while the Susanville Municipal Airport occupies the northern edge of the quadrangle. The map reveals a network of canyons and flats, including Bear Flat and Lowe Flat, carved by seasonal drainages like Baxter Cr and Bankhead Cr.
