Yucatán Peninsula

"The Yucatán Peninsula is so luch and is rich in history about the Mayan civilization. It's so ancient that everyone loved the Mayan history, even during the Spanish colonial era. Some don't care. Some hated it. I think there's something terrible happening today, judging by that weird sound."

--Su Ji-Hoon, The Demonic Portal

The Yucatán Peninsula (Spanish: Península de Yucatán), in southeastern Mexico, separates the Caribbean Sea from the Gulf of Mexico, with the northern coastline on the Yucatán Channel. 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. It is approximately 181,000 km2 (70,000 sq mi) in area, and is almost entirely composed of limestone.
