The Umatilla National Forest occupies this portion of the Blue Mountains, where the headwaters of the Tucannon River and Little Tucannon River have carved deep drainages into the high plateau. The map details a landscape defined by sharp topographical features such as Al Williams Ridge, Big Turkey Tail, and Green Ridge. This 2020 survey illustrates a modern recreation and wilderness management era, where access is maintained through a network of primary routes like Tucannon River Road and Patrick Grade.
