The rocks possess 'lithophonic' properties, meaning they produce musical tones when hit.
When removed from the boulder field, the rocks lose their unique ringing sound.
The boulder field was formed during the Triassic period, roughly 200 million years ago, due to volcanic activity.
High Falls, located on the park grounds, stands at approximately 55 feet tall.
The rocks contain high concentrations of iron and magnesium, which contribute to their density and acoustic resonance.
Ringing Rocks County Park is a 128-acre park famous for a seven-acre boulder field composed of igneous rocks that emit a metallic, bell-like chime when struck with a hammer. These diabase boulders are not native to the immediate surface and remain an area of scientific study regarding their acoustic properties. The park features the largest waterfall in Bucks County, High Falls, located along the park's trail system. Visitors can traverse the boulder field, though the ground is uneven and lacks defined walking paths. The park is managed by the Bucks County Department of Parks and Recreation and is open to the public year-round. It serves as both a geological curiosity and a recreational area for hiking.
The base of the High Falls waterfall provides the most visually striking natural composition.
Bring a hammer or a small mallet to strike the rocks and hear the metallic tones.
Wear sturdy, closed-toe hiking boots with thick soles to navigate the jagged and unstable boulder field.
Bring insect repellent as the wooded areas around the field can be prone to ticks and mosquitoes.
Avoid wearing flip-flops or open-toed sandals, as the sharp edges of the boulders and the uneven terrain pose a significant injury risk.
Do not attempt to move, spray-paint, or remove rocks from the boulder field to preserve the site's unique characteristics.
