About this map

Gifford Pinchot National Forest and the Mount St Helens National Volcanic Monument define this 1984 survey, which documents a landscape profoundly altered by the recent eruption of Mount St Helens. The map captures a moment of transition following the 1980 blast, specifically noting extensive areas of blowdown timber across the ridges and drainages. The east shore of Spirit Lake is clearly visible, showing the proximity of landmarks like Harmony Falls to the volcanic peak.

Drainage systems including Clearwater Creek, Green River, and Smith Creek are traced through the broken terrain. Higher elevations like Goat Mountain and Bismark Mountain stand as permanent landmarks amidst the changing forest, while numerous small backcountry lakes such as Panhandle Lake, Grizzly Lake, and Ghost Lake dot the high country. For those studying the immediate geographical aftermath of the eruption, these contours and annotations provide a precise record of the geological and botanical impact on the region.
