Ringing Rocks Park, Bucks County, PA

Wow!! What a fun day trip to Upper Black Eddy, PA to visit the infamous Ringing Rocks Park! Brought our hammers and cameras to capture this mysterious phenomenon. Just hammer down on some boulders and listen to the sweet ringing echos travel through the park. Also found out later that there are waterfalls lol ooops! Well what do you guys think cause the ringing noise? Drop a comment..
