One of the most massive volcanic eruptions ever investigated occurred in a valley in southern Alaska in 1912. The eruption covered over forty square miles with ash as deep as 210 meters and left thousands of vents (called fumaroles) in the valley spewing steam and gas.
Questions
1. How did this valley get its name, the Valley of Ten Thousand Smokes?
2. Why don’t you see any smoke in the photograph?
3. Name some other places where there are volcanoes.
