2020 Map of Mount Saint Helens

About this map

Mt Saint Helens stands as the central feature of this 2020 topographic study, documenting the complex recovery and geological shifts of the landscape decades after its major eruption. The detailed contours delineate the 1980 Crater and the emerging Lava Dome, providing a precise record of the current volcanic topography within the Gifford Pinchot National Forest. Glacial movement is still prominent, with the Toutle Glacier, Shoestring Glacier, and Dryer Glacier clinging to the slopes above the debris-filled drainage of the N Fork Toutle River. Surrounding the peak, the map traces modern recreational and research access, from the Climber's Bivouac and Monitor Ridge Climbing Route to the extensive trail network including the Loowit and Abraham trails that cross the Plains of Abraham. This recent survey serves as a vital record for geologists and hikers tracking the evolving terrain of the Swift Creek Flow and the volatile Lava Canyon.
