Summary

Description
English: Gravity anomaly map of the Chicxulub impact structure. The coastline is shown as a white line. A striking series of concentric features reveals the location of the crater. White dots represent water-filled sinkholes (solution-collapse features common in the limestone rocks of the region) called cenotes after the Maya word dzonot. A dramatic ring of cenotes is associated with the largest peripheral gravity-gradient feature. The origin of the cenote ring remains uncertain, although the link to the underlying buried crater seems clear.
