The Hoopa Valley Indian Reservation dominates the eastern boundary of this 1952 study, where the Klamath River carves through the landscape. This era reflects a transition in land use, balancing traditional territory with emerging ranching and fire management. A notable string of prairies—including Pitt Place Prairie, Hancorne Prairie, and Thompson Prairie—run along the Bald Hills Ridge, illustrating the distinctive high-elevation clearings that defined this part of Humboldt County.
