1998 Map of Mount St. Helens

About this map

Mount St Helens stands at the center of this landscape, its topography defined by the massive 1980 Crater and the emerging Lava Dome. This 1998 revision by the Forest Service illustrates a terrain in active transformation within the Mount St Helens National Volcanic Monument, where the northern face is dominated by The Breach and the expansive Pumice Plain. The survey details a complex system of ice and debris, including the Loowit Glacier, Forsyth Glacier, and Shoestring Glacier, alongside significant geological formations like the Floating Island Lava Flow. To the south, the environment transitions toward recreational and access points such as the Marble Mtn Sno-Park and Redrock Pass. The map serves as a precise record of the post-eruption recovery and the shifting boundaries between the Gifford Pinchot National Forest and the volcanic monument.
