Well, I for one was really impressed and amazed at the
exfoliation video. And I would not have seen it without Harvey's link.
When I was a geology student, even the professors did not have a good handle on why granite breaks up in that exfoliation pattern, and I was a student of some of the best. Now years later, the theories were put forth that the unloading of overloading rock somehow enabled the granite to expand, as if it were like a sponge.
Now this video appears, showing a truly rare event. For someone to be present on the granite slabs, to be video recording, and to capture the granite cracking and exploding like that, it's a much more rare event than ever being struck by lightning or winning a lottery.
"Amazing" just doesn't express the significance. Thank you Harvey for posting it.
