Ringing Rocks State Park

Ringing Rocks Park is a 128 acre park nestled in the woods in Upper Black Eddy. Located within the park is a field of boulders, about 7-8 acres in size, that have an unusual property. When the rocks are struck with a hammer or another rock, they sound as if they are metal and hollow and ring with a sound similar to a metal pipe being struck. The park also has Bucks County's largest waterfall.

Besides the strange ringing properties of the stones, there are other mysteries surrounding this park. One odd thing about the park is that most boulder fields are the result of an avalanche from a mountainside collapsing. This boulder field, however, is towards the top of the hill, not the bottom. That means it didn't result from a rock slide. There is also no evidence to suggest that these were dropped here by a glacier as glaciers were not thought to have come this far south. How did this boulder field get to be like this?
