Do you know the Chicxulub Crater? The Chicxulub Crater was 150 kilometer wide in diameter. Cenotes and the Ocean Lake Phenomenon are the positive results of Do you know the Chicxulub Crater? Knowledge of the size and internal structure of the Chicxulub crater is necessary for quantifying the effects of the impact on the Cretaceous environment. Although much information bearing on the crater's structure is available, diameter estimates range from 170 to 300 km (refs 1á¤-7), corresponding to an order of magnitude variation in impact energy.
