About this map

The Larabee Valley and surrounding hills of southern Humboldt County are defined by a network of family ranches and mountain camps in this late-1940s survey. Settlement patterns favor the river basins and ridgelines, with Blocksburg serving as a central hub for the isolated Gunlock Ranch, Cottrell Ranch, and Bliss Ranch properties. Educational and administrative infrastructure is visible through the remote Buck Mtn School, the Mad River Ranger Sta, and the Lassics Lookout positioned for forest monitoring.

Transportation is anchored by the Northwestern Pacific railroad along the Eel River in the southwest corner, while the Van Duzen River and its numerous tributaries like Larabee Creek carve the upland terrain. Unusual specialized agricultural sites are noted, such as the Snowline Fox Farm, providing a specific record of local industry before the modern era. High peaks like Mt Lassic and Red Mtn anchor the eastern boundary within the Trinity National Forest.
