A cenote (English: / s ɪ ˈ n oʊ t i / or / s ɛ ˈ n oʊ t eɪ /; Latin American Spanish:) is a natural pit, or sinkhole, resulting when a collapse of limestone bedrock exposes groundwater. The term originated on the Yucatán Peninsula of Mexico, where the ancient Maya commonly used cenotes for water supplies, and occasionally for ...
Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. [1] It has also been documented for weathering -resistant rocks, such as quartzite , given the right conditions. [ 2 ]
The following is a list of sinkholes, blue holes, dolines, crown holes, cenotes, and pit caves. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks [1] or suffosion processes. [2]
The Sacred Cenote at Chichen Itza. The Sacred Cenote (Spanish: cenote sagrado, Latin American Spanish: [ˌsenote saˈɣɾaðo], "sacred well"; alternatively known as the "Well of Sacrifice") is a water-filled sinkhole in limestone at the pre-Columbian Maya archaeological site of Chichen Itza, in the northern Yucatán Peninsula.
The brackish water flowing through the cenotes outflows along the sea shore, forming brackish coastal and submarine springs. The groundwater of Melissani cave outflows at the "Fridi" beach. This brackish water is part of a famous hydrogeological phenomena : seawater is sucked in the west part of the island of Kefalonia, near Argostoli, and ...

The two islands are the surface features of the undersea Barbuda Bank and have karst limestone landscapes. [1] Barbuda is primarily flat and formed from coral reefs . The Middle Miocene Highlands Formation has limestones which are the oldest rocks on the island, rising 120 feet above sea level.
Water temperature is 25 °C or 77 °F throughout the year, and the maximum depth near the Dos Ojos cenotes is approximately 10 meters (33 ft). The water is exceptionally clear as a result of rainwater filtered through limestone, and there being very little soil development in this region since the limestone is very pure.
