The Wetumpka impact crater is the only confirmed impact crater in Alabama, United States.It is located east of downtown Wetumpka in Elmore County.The crater is 4.7 miles (7.6 km) in diameter, and its age is estimated to be about 85 million years (late Cretaceous), [1] based on fossils found in the youngest disturbed deposits, which belong to the Mooreville Chalk Formation.
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 ...
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. 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]
For example, the Ishim impact structure [141] is conjectured to be bounded by the late Ordovician-early Silurian (c. 445 ± 5 Ma), [142] the two Warburton basins have been linked to the Late Devonian extinction (c. 360 Ma), [310] both Bedout and the Wilkes Land crater have been associated with the severe Permian–Triassic extinction event (c ...
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 ...
It may be an ancient asteroid impact crater. A man planning a camping trip using Google Maps ran across a uniquely curved spherical pit in Quebec. It may be an ancient asteroid impact crater.

A meteor crater over five miles in diameter was identified near Wetumpka, Alabama in 1969–1970. Conclusive evidence of the origin of the Wetumpka Impact Crater was found by Auburn University geology professor David T. King in 1998. [16]
