Ringing Rocks County Park

Bitter and I paid a visit here today, since it was such a lovely day

There is actually some debate as to the origin of the rocks.  Some folks suggest the Wisconsin ice sheet never made it down that far, but others have said:

While Pennsylvania’s boulder fields are characteristically situated closed to where the Wisconsin ice sheet once stood, there is one oddball exception located to the south of the glaciated part of the state, in the Triassic Lowland. This is the locally famous Ringing Rocks County Park — the county being Bucks, just a short distance from the Delaware River north of Philadelphia. Here the boulders are made of a much harder, igneous rock called diabase. This rock formed when magma welling up from the Earth’s interior during the rifting and breakup of the supercontinent of Pangea cooled close to the surface. In this particular park, the boulders are said to produce a variety of ringing tones when struck with a hammer.

I don’t know.  I think my Ron Paul theory is better.

    I just assumed they had a high metal content. Or they’re like geodes or something.

    Stupid geology.
