The N Fork Toutle River dominates the central landscape of this Cowlitz County survey, illustrating the complex drainage patterns below the Toutle Mountain Range. This 2013 topographic study shows the area's recovery and modification decades after the Mount St. Helens eruption, notably marked by the Debris Dam Viewpoint overlooking the valley floor. High-altitude peaks including Hoffstadt Mtn and Spotted Buck Mtn define the steep relief of the region, which is heavily managed by the Gifford Pinchot National Forest in the southeast corner.
