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 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.
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [3] and age, with some sources giving it as < 10 ka [2] [4] while the EID gives a broader < 100 ka. [3]
The authors also conclude that the primary causes of the subsidence in the southern Chesapeake Bay region are sea-level rise due to the melting of the Laurentide ice sheet, groundwater extraction on mainland Virginia, and the remaining effects of the Chesapeake Bay impact crater near Cape Charles, Virginia, 35.5 million years ago.
