Sitting in a forested area, the Ringing Rocks appear in a field that has no vegetation except for lichens. Ten feet thick and seven acres around, the rocks are composed of diabase, in other words part of the Earth's basic crustal structure. There is absolutely nothing strange or anomolous about them, except for the fact that when struck hard they ring. In June of 1890 Dr. Ott, along with a brass band, played several songs on the rocks for the enjoyment of the appreciative Buckwampum Historical Society. Ott learned what other investigators have since concluded: the rocks do not need to be in their natural place to ring nor do they need to be wholly intact. Curiously though made up of the same materials, not all of the Ringing Rocks ring, in fact studies show that only about 30% of them do so. Though this is more than likely a natural phenomenon, there has never been a satisfacory explanation proposed. In 1965 geologist Richard Fass of Lafayette College, Easton, Pennsylvania, conducted laboratory experiments using sensitive equiptment. He learned that when a ringing rock was struck, a series of subaudable frequencies were produced, and that these combined or added up to a tone which could be heard by the human ear. He could not offer any physical cause.
To claim this earthcache, send a picture of your group at the site. Also email cache owner how many rocks you hit and how many had a "ring" and why you think they sounded that way.
If you forgot a hammer, DaisyChain put one in the nearby cache. Recently I have been told that the hammer could not be found? You might plan on bring one. Thanks Janee!
