2017 Map of Elk Rock
USGS Topo · Published 2017About this map
Gifford Pinchot National Forest dominates this landscape in the years following the massive geographic shifts caused by volcanic activity in the region. The map documents a recovering environment where the N Fork Toutle River carves through a transformed valley floor, flanked by prominent elevations such as Elk Rock and Spud Mtn. The drainage patterns are clearly defined by numerous tributaries, including Hoffstadt Cr, Bear Cr, and Maratta Cr, which feed into the primary river system.
