Chicxulub Gravity Cap (IMAGE) University of Texas at Austin Caption The Chicxulub crater has been filled in by sediments over the millions of years since impact. Using a gravity map, the crater's topological features can be visualized. The red and yellow are gravity highs, and green and blue are gravity lows. The white dots indicate a network of sinkholes called "cenotes,"which were formed as a result of the impact.
