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]

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]
