About this map

Yale Lake and Lake Merwin dominate the northwestern portion of this terrain, where the Lewis River is impounded along the border of Cowlitz and Clark Counties. The landscape is defined by the sharp transition from these water bodies into the heavily forested uplands of the Gifford Pinchot National Forest. Geologic landmarks like the volcanic silhouette of Tumtum Mtn and the high points of Bare Mt and Green Knob overlook a dense network of drainages, including Siouxon Creek and Canyon Creek.

Evidence of local industry and specialized aviation appears at the forest's edge. The Chelatchie Prairie Mill Pond and NE Rotschy Mill Rd point to the area's timber history, while the Mount St Helen's Aero Ranch indicates a unique residential-aviation community tucked into the foothills. The road network, including Lewis River Rd and Yale Bridge Rd, provides the primary access to these remote reaches of the Pacific Northwest.
