Global Volcanism Program | Image GVP-02869
The lateral blast of the 18 May 1980 Mount St. Helens eruption removed large standing trees near the volcano. The high-velocity rocky flow left jagged stumps with splinters facing away from the volcano and parallel to the direction of movement of the flow. This tree is about 2 m high, located 9 km N of the crater on Harry’s Ridge.
