1954 Map of Yolla Bolly

About this map

The North Yolla Bolly Mts and their southern counterparts anchor this high-elevation wilderness where the borders of Trinity, Tehama, Mendocino, and Glenn counties converge. This 1954 survey by the Forest Service documents a landscape of remote camps and administrative outposts scattered across deep ridges and glades. Settlement is restricted to seasonal or specialized sites such as Weston Ranch and Johnson Hdqrs, while the Saddle Camp Guard Sta and various lookout points like Tomhead Mtn provide the only permanent infrastructure. The map reveals an intricate network of early trails, including the Humboldt Trail and N Yolla Bolly Trail, which served as the primary routes through the Yolla Bolly-Middle Eel Wilderness Area. For those tracing local history, the specific naming of remote glades like Murphy Glades and Appletree Glade provides a look into the grazing and forestry patterns of the mid-20th century, before more modern access reached these remote drainages.
