Located approximately 70 miles north of Portland, Ore., within theGifford Pinchot National Forest, the 110,000 acre Mount St. Helens National Volcanic Monument was established following the 1980 eruption of Mount St. Helens. The Monument was set aside for research, recreation, and education. Inside the Monument, the environment is being left to respond naturally to the disturbance. It is the first such monument managed by the U.S. Forest Service.
