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 North American tektite strewn field is a large area, known as a strewn field, in North America defined by the presence of tektites consistent with having come from the same bolide. The field is believed to be associated with the Chesapeake Bay impact crater. [1]
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 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.
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 ...
The Chesapeake Bay Bridge, connecting the eastern and western shores of Maryland was completed in 1952. Length of the suspension span is 2,922 feet and the roadway is about 200 feet above water at ...
Bediasite is a form or type of tektite, which is a body of natural glass formed from earth debris during meteorite impact events. [1] It originates in an area in the eastern part of the U.S. state of Texas centered on the small town of Bedias which is 74 miles (119 km) north west of Houston. [2]
