2012 Map of Holter Ridge

About this map

Holter Ridge defines the interior heights of this coastal Humboldt County terrain, where a complex network of drainages flows toward the Pacific and the Klamath River. The map documents a landscape primarily defined by its hydrology and high meadows, notably Bukers Prairie and Hancorne Prairie. These open spaces are connected by a system of rural routes such as Johnson Rd and Hancorne Ranch Rd, which follow the contours of the ridges and creek valleys. Numerous named water bodies like Tectah Cr, Mettah Cr, and Lost Man Cr carve through the area, indicating the dense drainage patterns characteristic of the region's northern forests. The presence of the Klamath River in the northeast corner serves as the primary geographical anchor, while smaller tributaries like Achelth Cr and Halagow Cr feed into its course.
