New York state’s hidden secret: A subterranean impact crater

I’ve heard of stealth bombers and stealthy ninjas and even a super-sneaky magnitude 8 earthquake, but until today I hadn’t heard about stealth craters: large features, more than three kilometers across and more than 300 meters deep-- definitely big enough to be obvious, one would think. But not if it's buried. One such crater lurks 1.2 kilometers underground in New York’s Finger Lakes Region. Located near Syracuse and close to the Bear Swamp National Forest, the crater is completely invisible from the surface.
