After the Chicxulub meteor impact about 66 million years ago, groundwater dissolved limestone beneath Mexico's Yucatán Peninsula, helping create the Ring of Cenotes. Individual cenotes can also form when cave roofs collapse. The video's speaker estimates that 260 to over 300 feet of limestone once roofed the cavern and that more than 100 feet later collapsed to form the sinkhole. The cited evidence concerns Yucatán, Mexico, and does not establish the same impact origin for Belizean cenotes.
Chicxulub impact helped form cenotes on Mexico's Yucatán Peninsula

Key facts
- The cited evidence concerns the Ring of Cenotes on Mexico's Yucatán Peninsula, not Belize.
- Impact-related groundwater flow dissolved limestone after the Chicxulub impact about 66 million years ago, helping form the cenotes; the supplied results do not establish the impact as the direct cause of cave-roof collapse.
- The 260-to-over-300-foot ceiling and more-than-100-foot collapse figures are the speaker's estimates, not findings attributed to scientists by the cited results.
- Cenotes can form through limestone dissolution followed by collapse of cave roofs.
