Ok – I have heard this but geologists should be ashamed of themselves. You have cameras among other technology which you could record it along with wind and other artifacts possibly causing the movement.
No one seems interested in doing so – yet the nuts will classify this in the paranormal category.
I think Dave F. is a hypocrite. He thinks that geologists should use there technology to figure it out. You don’t think they are trying? And if it is SOO easy to figure out, why doesn’t dave go figure it out? Why? Because HE doesn’t have the technology. So leave the geologists to do what they can when they can.
