2021 Map of Grays Peak

About this map

Lassen National Forest defines the eastern landscape of this high-elevation region, where the county line between Shasta and Tehama counties crosses complex hydrologic networks. The terrain is marked by significant drainages such as S Fork Digger Cr and Onion Cr, flowing through a series of canyons and gulches including Blue Lake Canyon and Dry Gulch. Historical land use is suggested by the presence of Forwards Mill Rd, a route hinting at the area's timber history, alongside names like Sugarpine Flat and Hazen Flat. High points such as Grays Peak and the prominent Blue Ridge divide the numerous springs and creeks, including Ward Springs and Sugarpine Spring, providing a detailed look at the watershed before it descends toward the Central Valley.
