The geographic land form named Yucatan Peninsula, or Península de Yucatán in Spanish, covers portions of three countries: Mexico, Guatemala and Belize.

The Yucatan Peninsula, and the corresponding DNA region, is surrounded by bodies of water on three sides, the largest two being the Caribbean Sea and the Gulf of Mexico. Interestingly, the Chicxulub crater – one of the most consequential craters in earth’s history and the one that likely caused the extinction of the dinosaurs, was discovered right off the coast of the peninsula in the Gulf of Mexico.

The crater caused the creation of cenotes, which are beautiful, natural, water-filled pits. These pits have historically been important water sources for the Maya inhabitants of the Yucatan Peninsula, and have become famous tourists destinations in modern times.
