humanoidhistory:May 18, 1980: Mount St. Helens erupts in Washington State with an explosive column rising 80,000 feet into the atmosphere, raining down ash in 11 U.S. states. The eruption melts mountain ice and a few whole glaciers, forming a series of massive volcanic mudslides that reach as far as the Columbia River, almost 50 miles away.(USGS) -- source link
