Cenote Angelita

Cenote Angelita lies inland from Tulum on Mexico's Yucatan Peninsula, a deep, roughly cylindrical karst sinkhole formed by the collapse of limestone into an underlying flooded cavern. Its distinguishing feature sits at a depth of roughly thirty meters, where a dense layer of hydrogen sulfide, produced by decomposing leaf litter and organic matter washed in from the surrounding jungle, forms a cloudy, sharply defined band suspended between the fresh water above and denser saline water below. From within the cenote this layer resembles a river or mist flowing along the cave floor, complete with the appearance of submerged tree trunks and branches around its edges, an illusion that gives the site its name, meaning Little Angel. This entity documents Cenote Angelita specifically as a geological formation, a karst sinkhole known for the visually distinctive hydrogen sulfide layer suspended partway down its flooded shaft.
