Did you know about the "crater" in the Catskills?The circular pattern made by the two creeks surrounding Panther Mountain suggest that it might have a different origin from other Catskill peaks. In the early 1970s, a geologist of the New York State Geological Survey at the New York State Museum in Albany wondered if the stream pattern indicated an impact crater buried beneath the surface.
The impact is estimated to have occurred 375 million years ago, during the Devonian period, when much of what is now the Catskills was either river delta or a shallow sea. The crater lies 2,640 feet below the surface, is 6 miles wide, and lies directly under the mountain. The meteorite that struck is believed to have been roughly one-half mile wide, striking with a force equivalent to 11 trillion tons of TNT. -Wikipedia
