Yucatan chix crater

The Yucatan peninsula and the Chicxulub crater.

The Yucatán Peninsula, in Southeastern Mexico, separates the Caribbean Sea from the Gulf of Mexico. The peninsula lies east of the Isthmus of Tehuantepec, a northwestern geographic partition separating the region of Central America from the rest of North America.


Battle of EarthEdit

During the Covenant occupation of Earth in 2552, the Covenant conducted extensive underwater excavation operations in the area, looking for Forerunner artifacts, likely due to the presence of the Chicxulub crater. Blue Team, comprised of Spartans -104, -058 and -043, stopped these operations.[1]
