Where is the Chicxulub impact crater?

The Chicxulub impact crater is buried under the Yucatán Peninsula in Mexico and extends offshore into the Gulf of Mexico. It is about 180 km wide and is linked to the asteroid impact 66 million years ago that helped trigger the extinction of the non-avian dinosaurs. The crater was identified through geophysical studies rather than by a visible surface ring. It is one of the most important impact sites in Earth history.
