2017 Map of John Day Mountain

About this map

Nez Perce National Forest defines this high-elevation landscape in Idaho County, where the terrain is marked by prominent crests such as Arrison Ridge and Brushy Ridge. The eponymous John Day Mountain stands as a central landmark, part of a complex drainage system where the S Fork John Day Cr and E Fork John Day Cr converge. This 2017 survey details the remote forest road network, including Nut Basin Rd and John Day Rd, which provide access to high-country features like Nut Basin Lake and Martin Spring. The map provides a clear record of the watershed, showing how numerous gulches like Henry Gulch and Bear Gulch feed into the primary creek systems, while significant overlooks like Slate Point and Dead Point dominate the eastern ridges.
