2018 Map of High Plateau Mountain

About this map

The North Fork Smith River carves a deep path through this borderland where Del Norte County, California meets Curry County, Oregon. This 2018 survey illustrates a landscape dominated by the overlapping boundaries of the Siskiyou National Forest and Six Rivers National Forest. The map captures a topography defined by steep ridges and canyons, including the prominent High Plateau Mtn and the uniquely named Peridotite Canyon. Transport through this wilderness is limited to legacy routes like Low Divide Rd and Wimer Rd, which follow the difficult contours of the land. In the southern portion of the sheet, Gasquet Mtn and Elk Camp Ridge stand as significant landmarks, while numerous tributaries such as Eighteenmile Cr and Twelvemile Cr drain into the primary river system, reflecting the complex hydrology of the Klamath Mountains.
