About this map

The confluence of the Eel River and the Middle Fork Eel River defines this Mendocino County landscape, where the small settlement of Dos Rios serves as a focal point for the surrounding canyon country. This 2018 survey documents a region of steep ridges and numerous drainages, including Burger Creek and Poonkinny Creek, which feed into the primary river systems. To the south, the rail-aligned community of Tatu sits along the riverbanks, connected by the Laytonville Dos Rios Rd.

High-elevation features such as Big Chemise Knob and Little Chemise Knob overlook the deeply carved canyons of Little Water Canyon and Big Water Canyon. The map reveals a network of remote lakes and valleys, from Howard Lake and Grassy Lake in the east to the tucked-away Rodeo Valley in the south. These topographic details illustrate the challenging terrain that has historically dictated the routes of local thoroughfares like Poonkinney Rd.
