Today’s Mount St. Helens quiz:
QUESTION: Name the four other Holocene volcanoes in Washington State besides Mount St. Helens?
ANSWER: Find out tomorrow on Ear to the Ground …or… see the answer now on DNR’s Facebook page
Yesterday’s QUIZ: Question: How many board feet of standing timber (trees) was blown down by the Mount St. Helens blast and smaller eruptions in the following days? A: 4 billion board feet – enough lumber to build 200,000 new 2,000-square-foot homes (Realty Times).
What does one do with millions of tons of volcanic ash? If you are a scientist, you can watch what happens naturally over decades as researchers are doing at the Mount St. Helens National Monument. But for cities, counties and landowners across Eastern Washington, the question was hardly academic. In the months and years following the volcano’s May 18, 1980, eruption, they had a lot of ash to deal with.
How about using it in bricks, pavement, paint, glass, waste treatment or other uses? Many asked and here are answers in this 1981 DNR monograph: Mount St. Helens Ash: Properties and Possible Uses.” See our Mount St. Helens information page for more links about volcanoes.
