Man catches explosion on tape
In Sierra Nevada, someone managed to capture something interesting on film. The process caused exfoliation, which is a form of mechanical weathering in which curved slabs or rock detach and slough off from the rock underneath. The ongoing exfoliation at Twain Harte Lake in Sierra Nevada (starting august 3rd) outcrops of granite have been furiously exfoliating, and one Youtube user managed to capture it. Here is were it can be viewed.
