Excellent post! I have heard of most of these except Mels Hole and the ringing rocks, which are here in PA where i live! Maybe I will have to take a trip down there before I leave the state. I wonder what would happen if I bombard them with certain sound frequencies??
I am also very excited to move to Oregon so I can check out the Oregon Vortex. There are a number of tests and experiments I would love to do in and around it, if they let me. For example examining it at different wavelengths of light, certain magnetic experiments, tests with sound and vibration. Hell, I may just sit in the middle of it and meditate!!!
