Cenote at Bolonchén, Mexico, used as a source of water, painting of 1842 by Frederick Catherwood. In the north and northwest of the Yucatán Peninsula in Mexico, the cenotes generally overlie vertical voids penetrating 50 to 100 m (160 to 330 ft) below the modern water table. However, very few of these cenotes appear to be connected with ...
Zacatón is a thermal water-filled sinkhole belonging to the Zacatón system – a group of unusual karst features located in Aldama Municipality near the Sierra de Tamaulipas in the northeastern state of Tamaulipas, Mexico. At a total depth of 339 meters (1,112 ft), it is one of the deepest known water-filled sinkholes in the world. [1]
It is about 60 metres (200 ft) in diameter and about 48 metres (157 ft) deep. [1] A carved stairway leads down to a swimming platform. Cenote Ik Kil is near the Maya [2] ruins of Chichen Itza, on the highway to Valladolid.

Dos Ojos contains the deepest known cave passage in Quintana Roo with 119.1 meters (391 ft) of depth located at "The Pit" discovered in 1996 by cave explorers who came all the way from the main entrance some 1,500 meters (4,900 ft) away. The deep passages include the "Wakulla Room", the "Beyond Main Base (BMB) passage", "Jill's room" and "The ...
Bottomless Lakes State Park – Lazy Lagoon Lake, New Mexico, made up of three separate sinkholes; Cedar Sink – a vertical-walled large depression in Kentucky. Daisetta, Texas – sits on a salt dome, in 1969, 1981, and again in 2008, sinkholes formed in the area; Deep Lake (Florida) – a natural sinkhole in Big Cypress National Preserve in ...
In 1978, geophysicists Glen Penfield and Antonio Camargo were working for the Mexican state-owned oil company Petróleos Mexicanos as part of an airborne magnetic survey of the Gulf of Mexico north of the Yucatán Peninsula. [14]: 20–21 Penfield's job was to use geophysical data to scout possible locations for oil drilling. [5]
The main camp of exploration became Cenote "Far Point Station", located 6 kilometers (3.7 mi) from the coast, and 2.8 kilometers (1.7 mi) further inland than Main Base Camp situated at the main Nohoch Nah Chich Cenote entrance. During the Nohoch 1997 expedition, the 60 kilometers (37 mi) of total explored cave passage mark was surpassed.
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 ...
