A lot of rock smashed to pieces, perhaps? Do you see it? Ditto for decades. What conditions are necessary to form rock quickly. Lava is quick but doesn't form that kind of rock. But anyway, to form it in decades, what conditions have to prevail? Do you see traces? I can't answer, but I expect the geologists who listened to Hutton's talk could.
