This view from above the south rim of the crater of Mount St. Helens shows the lava dome partially filling the crater on 28 October 1986, at the very end of the 1980-86 eruption. After six years of episodic growth the lava dome reached a height of 250 m and a diameter of 1,100 m. Photo by Lyn Topinka, 1986 (U.S. Geological Survey).
