Ames crater is a meteorite crater (astrobleme) in Major County, Oklahoma, United States. It is about 3 kilometres (1.9 mi) north of Ames, Oklahoma[1] and 30 miles (48 km) southwest of Enid, Oklahoma.[2] Buried under a thick layer of sediment, it was not discovered until 1991.

Subsequent drilling within the crater, found a large amount of oil and gas. It is one of the largest of six meteor craters associated with oil-producing formations in the United States.

Ames Crater is 10 miles (16 km) in diameter and the age is estimated to be 470 ± 30 million years (Ordovician).

 The crater is not exposed at the surface.[3] It may be one of several Middle Ordovician meteors that fell roughly simultaneously 469 million years ago, part of a proposed Ordovician meteor event, including the Decorah crater in Iowa, the Slate Islands crater in Lake Superior, and the Rock Elm crater in Wisconsin.[4]

When the meteor struck, this part of the earth was covered by a shallow sea.

The object, traveling at an estimated speed of 70,000 mph (110,000 km/h), created a crater in the earth's crust. This created enormous pressures below the point of impact, which made the remnant of the meteorite recoil slightly, creating an uplift.

The sea returned and over eons, deposited layers of sediment.

 Other geological movements tilted the formation slightly. The sea eventually disappeared, leaving the crater buried in the earth, invisible from the surface.

It was discovered by Rex Olson in 1991 as he was studying a map generated using data from seismic tests.
