BTW, are you familiar with how they first discovered the supervolcano under Yellowst one?
Years ago, a geologist was rowing across the lake early one spring.. As he got to shore, he noticed that all the trees on one end were dying., because they were submerged under several feet of water. The deformation of the caldera under the lake had pushed water to the edges, and it rose.
Talk about an AHA!!! moment
Now that you mention it and relate the story ... it does sound familiar.
Something other than “Ah-hah” came to mind, but I know where you’re going with that...lol!
