Blast Edge Viewpoint; Monument Entry

The lateral blast during the 1980 eruption thundered across the landscape as far as 17 miles from the volcano, blasting away, flattening or leaving standing dead trees. Stop and marvel at the still-standing dead trees killed by the heat during the eruption at the outer edge of the blast zone. The site marks the eastern entrance to the Mount St. Helens National Volcanic Monument.
