2018 Map of High Divide

About this map

High Divide and Low Divide sit at the center of this remote topographic survey along the Oregon-California border, where the Klamath Mountains meet the Pacific drainage. This 2018 edition illustrates the complex hydrography of the region, including the headwaters of the S-Fork Winchuck River and the North Fork Smith River. The map captures a landscape defined by forest management boundaries, split between the Siskiyou National Forest and Six Rivers National Forest. A network of unpaved forest arteries, such as Low Divide Rd and Rowdy Creek Rd, provides the primary access through this heavily dissected terrain. From the waters of Wimer Spring to the drainage of Hardscrabble Cr, the map serves as a contemporary record of the natural landmarks and relief features that have long shaped travel and land use in Del Norte County and Curry County.
