1958 Map of Mt St. Helens

About this map

Mount St Helens dominates the landscape in this mid-century survey, shown prior to its transformative 1980 eruption. The peak is detailed with landmarks such as Goat Rocks, Sugar Bowl, and the False Summit, surrounded by the extensive Gifford Pinchot National Forest. To the south, the recently completed Swift Reservoir on the Lewis River has altered the valley floor, creating a massive water body where the Marble Creek and Swift Creek once met.
