Umatilla National Forest defines this high-elevation landscape in the mid-1990s, where the boundary between Morrow and Umatilla counties cuts through dense timber and open meadows. The area is characterized by a series of high-altitude grasslands including Matlock Prairie, Balsinger Prairie, and North Prairie, which stand out against the surrounding forest. Central to the map's geography is the Blue Mountain Scenic Byway, which provides access to remote landmarks like the Ellis Forest Service Station and the Fivemile Cow Camp. To the west, Arbuckle Mountain overlooks the drainage of Fivemile Creek. Numerous springs, such as Happy Home Spring and Sulphur Spring, are scattered across the terrain, indicating the vital water sources that supported early seasonal grazing and forestry operations. Historical transit is marked by several named routes including the Turpentine Trail and Freezout Trail.
