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. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...

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 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.

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 crater is exposed to the surface, rising 160 m (520 ft) above the surrounding tundra, and is 400 m (1,300 ft) deep.The 267 m-deep (876 ft) Pingualuk Lake fills the hollow, and is one of the deepest lakes in North America.
