Six Rivers National Forest encompasses much of this terrain in Trinity County, where a complex network of ridges and watercourses defines the landscape. The Eel Wild and Scenic River and the North Fork Eel River serve as primary drainage systems, joined by numerous tributaries such as Cottonwood Cr and Willow Cr. Notable landmarks like Schoolhouse Spring and Climbing Spring suggest points of significance for water access in this elevated environment. The topography is anchored by prominent features including Long Ridge, Haman Ridge, and Russell Ridge, which are traversed by essential routes such as Long Ridge Road and Zenia Lake Mtn Road. This survey documents the intersection of protected wilderness areas and the necessary infrastructure for forest management and local access in the modern era.
