Six Rivers National Forest dominates this section of Humboldt County, where steep elevation changes are defined by a series of prominent ridges and peaks. High points like Horse Mtn, Spike Buck Mtn, and the namesake Grouse Mtn anchor the terrain. The landscape is a complex network of hydrologic features, including Clear Lake, Mud Lake, and numerous seasonal flows such as E Fork Willow Cr and Old Campbell Cr. Historically significant naming conventions are evident in landmarks like Titlow Hill and Gunrack Ridge.
