The Coweeman River and the South Fork Toutle River define the drainage of this high-elevation terrain in Cowlitz County. The landscape is characterized by a dense network of numbered logging routes, such as Logging 1600 Rd and Rose Valley Rd, which provide access to the timber-rich ridges including Baird Mtn and Nineteen Mtn. These peaks surround several named basins, most notably the area near Wolf Point and the high summit of O'Neil Peak. A significant water feature, Washboard Falls, is located along the Coweeman, marking a sharp descent in the river's path. Small tributaries with numerical names like Thirteen Cr and Twenty-one Cr flow through the deep valleys between the prominent peaks of the southern Cascades foothills, reflecting the systematic naming conventions used by early forest managers and surveyors in the region.
