The impact crater was formed approximately 360 million years ago as a shallow, saucer-shaped crater, 3.8 kilometres (2.4 mi) in diameter and about 150 metres (490 ft) deep. A large central hill, highly deformed rim strata, and a breccia lens 40 m (130 ft) in thickness were produced during formation. Over 2 square kilometres (490 acres) of flat ...
Wells Creek crater. / 36.37778°N 87.65833°W / 36.37778; -87.65833. Wells Creek is an impact crater located near Cumberland City, Tennessee. It is 12 kilometers (7.5 mi) in diameter and the age is estimated to be 200 ± 100 Ma (million years old), placing it in the Jurassic or a neighboring period. The crater is exposed to the surface.

Universe Today reports that researchers have developed a system that has autonomous drones use machine learning to find the smaller meteorites in impact sites that are either 'hidden' (even if ...
The Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory, Ottawa, under the direction of Carlyle S. Beals. Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
Map all coordinates using OpenStreetMap. 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 ...
"Meteorite impacts generate high temperatures ranging from 2,000-6,000 degrees Celsius (3,600-10,800 degrees Fahrenheit). These extreme temperatures melt and vaporize rocks on the lunar surface ...
