Ringing Rocks Park
Ringing Rocks Park is a county park in Upper Black Eddy, Pennsylvania at 40°33′47″N 75°07′37″W / 40.56316°N 75.12689°W / 40.56316; -75.12689. The ringing rocks in that area are diabase. In 1965, geologist Richard Faas of Lafayette College took a few of the rocks back to his lab for testing. He found that when the rocks were struck they created a series of tones at frequencies lower than the human ear can hear. An audible sound is only produced because these tones interact with each other. Although Faas's experiments explained the nature of the tones, they did not identify the specific physical mechanism in the rock which made them.

Borrow a child and stay in the house all day with the child,

to the welfare office and cry and say your man left you and
be humble and wear your dress and your smile, and don’t talk
back ...”
