Dive-site story
Cenote Sabak Ha is an open-air sinkhole in the south-central Yucatán plains, known among technical divers as the deepest explored cenote in the state. Sheer limestone walls plunge from the surface opening directly into a vertical shaft. Below surface organic matter, a dense hydrogen sulfide layer hangs over undisturbed freshwater and immense lower chambers. Daylight disappears rapidly beneath the rim, necessitating redundant illumination and technical cave protocols.
