At a total depth of 339 meters (1,112 ft), it is one of the deepest known water-filled sinkholes in the world. [ 1 ] Using an autonomous robot, the underwater portion of Zacatón has been measured to be 319 meters (1,047 ft) deep (a 20-meter (66 ft) difference between the rim of cliff and surface of water adds to the total depth).

The Sacred Cenote at Chichen Itza, Mexico. Cenotes are surface connections to subterranean water bodies. [5] While the best-known cenotes are large open-water pools measuring tens of meters in diameter, such as those at Chichen Itza in Mexico, the greatest number of cenotes are smaller sheltered sites and do not necessarily have any surface exposed water.
Considered one of the largest sinkholes (dolinas) in the world; Gruta do Centenário – a cave located in Mariana, Minas Gerais, the largest and deepest quartzite cave in the world, and second in the country in terms of unevenness; Lapa Terra Ronca – a dolomitic limestone cave inside the area of the Terra Ronca State Park in Goiás.
The cenote was once the city’s water source. [4] The cenote is in a partially collapsed cavern. [3] The cave is 150 feet across and 260 feet deep. [1] There are some stalactites on the ceiling of the cave. [3] There is a sloped passage with stairs carved from the rock that lead down to the water. [1] It is larger and more open than most other ...
The smaller Dos Ojos became a part of Sac Actun, making the Sistema Sac Actun the longest known underwater cave system in the world. [2] Dos Ojos lies north of the rest of the Sac Actun cave system. As a separate system, Dos Ojos remained in the top ten, if not the top three, longest underwater cave systems in the world since the late 1980s. [3]
Three prehistoric human remains have been found within the subsystem. The Jailhouse cenote, or Las Palmas, is the entrance to the locations of the Muknal and Las Palmas caves. The skeleton of an 18 to 20-year-old woman, Eve of Naharon, (13,454±117 cal BP) was discovered at a location around 368 m (1,207 ft) away from the Jailhouse cenote entrance.
Sinkholes known as cenotes connect the cave systems to the atmosphere; often older cenotes contain turbid, stagnating water with oxygen-rich and oxygen-poor layers. [1] That includes El Zapote, where the oxygen content drops in the halocline to anoxia , [ 27 ] while the freshwater layer contains oxygen; [ 28 ] the saltwater layer may [ 27 ] or ...
The Xiaozhai Tiankeng is 626 meters (2,054 feet) long, 537 meters (1,762 feet) wide, and between 511 and 662 meters (1,677 and 2,172 ft) deep, with vertical walls. Its volume is 119,349,000 m³ and the area of its opening is 274,000 m 2. This material has been dissolved and carried away by the river.
