Hells Canyon dominates this 2017 survey, where the border between Idaho and Oregon follows the dramatic drop in elevation toward the Snake River. The landscape is defined by the high ridges of the Wallowa National Forest and Nez Perce National Forest, including Grizzly Ridge and Monument Ridge. A few remote access points are documented, notably the Memaloose Airport situated on a high plateau. High-elevation vantage points like Hat Point and Granny View Point provide sweeping views of the river drainage system, which is carved by numerous seasonal streams such as Temperance Cr and Lightning Cr. The map captures a wilderness area where human footprints are limited to forest roads like Hat Point Rd and Snake River View Rd, and natural water sources such as Sacajawea Spring and Hoodoo Spring are critical landmarks.
