Visitor Tips and News About Ringing Rocks Park
Ringing Rocks Park
Seems to work with a hammer that some kids were using when we stopped by.[Evan, 08/25/2012]
Pottstown is in Montgomery County close to the Chester County border on Rt. 663. Ringing Rocks Park is [north of Pottstown in Pottsgrove]. Not many visitors come through. There are pavilions for picnics and a lot of shade trees. Not much else to do in this area. It is an interesting place but is always quiet.[T.J. Carroll, 03/09/2004]
Mysterious Ringing Rocks
Ringing Rock Park is located near the town of Pottstown [in Pottsgrove]
I first tried to hit the rocks using the rental mini-van metal jack, but no tones were produced. Some of the larger boulders produced some bell-like tones when stuck with a 10 pound rock.
The boulders themselves are basaltic rocks that intruded into the surrounding red shale (or so says the Philadelphia Mineralogical Society). After doing some web research, it appears that the best implement to produce sound is a hammer of some kind. One web page states that different hammers will produce different sounds when hit against the same rock. Perhaps a light claw hammer and a 2-pound sledge hammer would make for an interesting set of drum sticks.[Greg Brown, 05/13/2001]
