While on a visit to the Pacific Northwest you stop at Crater Lake, Oregon to enjoy the pristine beauty of the area. A friend traveling with you makes a comment that indicates that she thinks that the lake fills the solidified top of an extinct volcano. Educate your friend briefly using what you know about the area from the text
What will be an ideal response?
ANSWER: Actually, the lake is what’s left of a whole mountain; the top was much higher than this. There was an incredibly huge eruption here a long time ago. For a long time, people thought that the top part of the mountain had been blown to pieces, but now they realize that the whole top of the mountain sank down into the magma and basically just sank back down into Earth. Even though it has been a long time since the big eruption, this is still an active volcano.?
