1983 Map of Goat Mountain

About this map

Mount St Helens National Volcanic Monument dominates the eastern boundary of this map, recorded just years after the 1980 eruption. The landscape shows the immediate geological aftermath, with labels like "Eruption Line" and numerous Borrow Pits and gravel extractions indicating the massive civil engineering and recovery efforts underway in the early 1980s. The South Fork Toutle River cuts through the center of the terrain, flanked by Disappointment Ridge and Spud Mtn. Within the Gifford Pinchot National Forest, high-elevation features like Goat Mtn and the tranquil Goat Marsh remain distinct. Hydrological patterns are well-documented, from the headwaters of the Kalama River to smaller alpine features like Blue Lake and McBride Lake, providing a clear record of the region's topography during a period of profound environmental change.
