Six Rivers National Forest landscape is defined by the steep elevation changes of Haman Ridge and the winding course of the Eel River in the late 1960s. This survey reveals a pattern of isolated ranching and resource extraction, with Jamison Ranch, Lampley Ranch, and Lake Mountain Ranch marking the habitable pockets within the valleys. The presence of the Northwestern Pacific Railroad and its tunnel near Island Mountain highlights the critical transportation engineering required to navigate this portion of Trinity County.
