2018 Map of Grays Peak

About this map

Lassen National Forest terrain dominates this northern California landscape, where the volcanic geography of the Cascade Range is evident in the prominent rise of Grays Peak and the high elevations of Blue Ridge. The area is defined by a network of drainage systems including Digger Cr, Onion Cr, and the headwaters of Panther Cr. These watercourses have carved out significant features like Snoqualmie Gulch and Blue Lake Canyon. Transportation through this timber-rich environment is facilitated by the Mineral-Viola Hwy and a complex of logging roads such as Forwards Mill Rd and Blue Ridge Rd. The presence of numerous named water sources like Rock Spring, Blue Ridge Spring, and Rattlesnake Spring highlights the area's hydrology, while names like Sugarpine Flat and Hazen Flat indicate more level clearings amidst the steep ridges and gulches.
