Burnt Ridge and Threemile Ridge define the steep, drainage-heavy terrain of this Douglas and Coos County borderland during the late 1980s. The landscape is characterized by a dense network of watercourses, including the Williams River and the Brewster Fork Coquille River, which carve through the high elevations of Mount Gurney and Bear Mountain. Human presence is marked by the small settlement of Tioga and several localized industrial sites labeled simply as Quarry. The map provides a detailed view of local recreation and memorial spaces, specifically the Severt Iverson Memorial County Park and Dave Busenbark County Park, located along the southern reaches of Tenmile Creek. Notable natural landmarks such as Lost Creek Falls and the jagged prominence of Buzzard Rock stand out as significant topographic features in this heavily timbered region of the Pacific Northwest.
