2023 Map of Elk Rock

USGS Topo · Published 2023

About this map

Mount Saint Helens National Volcanic Monument defines this landscape, illustrating the dramatic geological shifts within the Gifford Pinchot National Forest. This modern record details the transformed drainage patterns of the North Fork Toutle River, where the massive debris avalanche from the 1980 eruption reshaped the valley floor. The formation of Coldwater Lake and Castle Lake is clearly visible, created when volcanic material dammed existing creek valleys. Significant topographic landmarks like Elk Rock and Spud Mtn tower over the sediment-filled basins. For researchers, the map provides a precise layout of the recovery-era recreational infrastructure, including the Hummocks Trl, Elk Bench Trl, and Lakes Trl, which navigate the hummocky terrain and the evolving shoreline of the post-eruption lakes.
