Blocksburg serves as the primary hub in this corner of Humboldt County, positioned along Alderpoint Rd where it meets Church St. The settlement is defined by its relation to the rugged drainage systems of the California Coast Ranges, specifically the south-flowing Larabee Cr and its numerous tributaries like McMahon Cr and Thurman Cr. The western edge of the map reveals the winding path of the Eel River, which flows past the small clusters of Eel Rock and Oak Glen. This terrain is punctuated by distinctive high points and plateaus, including Billy Goat Peak, Great Butte, and the colorfully named Blue Jacket Butte and Yellow Jacket Butte. These peaks and the associated Boulder Flat suggest a landscape largely shaped by its steep relief and the complex network of creeks that feed into the Eel River basin.
