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.

Famous quotes containing the words ringing, rocks and/or park:
“When we reached the lake, about half past eight in the evening, it was still steadily raining, and harder than before; and, in that fresh, cool atmosphere, the hylodes were peeping and the toads ringing about the lake universally, as in the spring with us. It was as if the season had revolved backward two or three months, or I had arrived at the abode of perpetual spring.”
—Henry David Thoreau (1817–1862)
“In a coign of the cliff between lowland and highland,
At the sea-down’s edge between windward and lee,
Walled round with rocks as an inland island,
The ghost of a garden fronts the sea.”
—A.C. (Algernon Charles)
“Is a park any better than a coal mine? What’s a mountain got that a slag pile hasn’t? What would you rather have in your garden—an almond tree or an oil well?”
—Jean Giraudoux (1882–1944)
