The Mount St. Helens Volcanic National Monument and the Gifford Pinchot National Forest define this landscape as it was documented in the late 1990s. The topography is marked by the dramatic descent of the Muddy River and Smith Creek, which carve deep paths through the high-elevation terrain near Smith Creek Butte. Evidence of volcanic activity and geomorphology is central to this survey, highlighted by features like the Lahar Viewpoint and the Ape Canyon Trail (Interpretive 234). Trace the drainage patterns of Clearwater Creek and Bean Creek as they flow through the protected forest. For researchers and hikers, the map identifies specific landmarks like the Jackpine Shelter and Moss Spring Viewpoint, alongside the interpretive routes of the Lava Canyon Trail.
