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.
Bones and pieces of jewelry have been found in the waters of the cenote by archaeologists and speleologists. [3] The cenote is part of a complex that includes a restaurant and hotel. [3] Ik Kil was a location on the Red Bull Cliff Diving World Series in 2010, 2011 and 2014. [4] [5] Stairs to access
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.
On-shore caves of similar formation, as large collapsed sinkholes, are well known in Belize and in the Yucatán Peninsula, where they are known as cenotes. Unlike the mainland cenotes which often link to underwater cave systems, there is little evidence of horizontal development in the Blue Hole. [citation needed] [clarification needed]
Dashiwei Tiankeng in Guangxi, China, is 613 m (2,011 ft) deep, with vertical walls. At the bottom is an isolated patch of forest with rare species. [61] The Dragon Hole, located south of the Paracel Islands, is the deepest known underwater ocean sinkhole in the world. It is 300.89 m (987.2 ft) deep. [62] [63]
A team of California researchers surveying satellite images found a cenote ring centered on the town of Chicxulub Pueblo that matched the one Penfield saw earlier; the cenotes were thought to be caused by subsidence of bolide-weakened lithostratigraphy around the impact crater wall. [18]
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.
