Which cave in Mexico is the deepest in the Western Hemisphere? Sistema Huautla is the correct answer.

Sistema Huautla is a vast cave system in Oaxaca, southern Mexico. It extends approximately 1,560 meters from its highest known entrance to its lowest reached point, making it the deepest cave system in the Western Hemisphere.

The system contains numerous entrances and more than 100 kilometers of surveyed passages. Its caves lie beneath the Sierra Mazateca and include major passages, shafts, sumps, and underground rivers.

Exploration has continued for decades, with cave divers and expedition teams reaching progressively greater depths. The system is also ranked among the world’s deepest caves, although its precise measurements and mapped length have changed as exploration progressed.
