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 Chesapeake Bay (/ ˈ tʃ ɛ s ə p iː k / CHESS-ə-peek) is the largest estuary in the United States. The bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula, including parts of the Eastern Shore of Maryland, the Eastern Shore of Virginia, and the state of Delaware.
The watershed of the entire Chesapeake Bay covers 165,760 km 2 (approximately 64,000 mi 2 or 41 million acres [3] [4]). With an estuary water body area of only 11,600 km 2 (4,479 mi 2), [5] the land-to-water ratio is about 14:1. [6] Therefore, the rivers flowing into the Chesapeake Bay have a large influence on water quality in the estuary.
