Tomorrow is the 30th anniversary of the eruption of Mount St. Helens. The May 18 eruption began with a massive landslide that collapsed the face of the mountain and then an explosion at 8:32 a.m. which lasted for nine hours, spewing hot ash and gases — dramatically altering the landscape around it.
QUESTION: How high did the column of ash reach into the atmosphere following the eruption?
See the answer on tomorrow’s Ear to the Ground …or… see the answer now on DNR’s Facebook page (while you’re there, please “fan us” — we’ve got plenty more information about Mount St. Helens coming in the next few days.)
Yesterday’s QUIZ: Q: Who renamed Mount St. Helens to replace the Native American name and who did he honor with the new name? A: In 1792, Captain George Vancouver of the British Royal Navy named the mountain in honor of his friend Alleyne Fitzherbert. Baron St. Helens.
