The Chesapeake Bay impact crater is a buried impact crater, located beneath the mouth of Chesapeake Bay, United States. It was formed by a bolide that struck the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch. It is one of the best-preserved "wet-target" impact craters in the world. [3]
The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed.
The oval, bowl-like valley (or "cove") is known for its fertile land and was once the bed of an ancient sea.About 8.5 miles (13.7 km) long and 4 miles (6.4 km) wide, it resembles a large asteroid impact or volcanic crater in satellite photographs and on topographic maps; however, it is actually a dome-shaped geologic up-warp that exposed older Ordovician aged limestone which is much more ...

If the team can determine the site is a crater formed by an ancient impact event, then the next step is researching just when it happened. Of the world’s roughly 200 impact craters, 31 are ...
