Yucatan chix crater

Battle of Earth[]

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]
