Cenote In Valladolid Mexico (21362599476)
A cenote ( or ; ) is a natural pit, or sinkhole, resulting from the collapse of limestone bedrock that exposes groundwater. The regional term is specifically associated with the Yucatán Peninsula of Mexico, where cenotes were commonly used for water supplies by the ancient Maya, and occasionally for sacrificial offerings. The term derives from a word used by the lowland Yucatec Maya——to refer to any location with accessible groundwater. Similar rock-sided sinkholes like cenotes are common geological forms in low-altitude regions, particularly on islands, coastlines, and platforms with young post-Paleozoic limestone with little soil development. The term ''cenote'' has also been used to describe similar karst features in other countries such as Cuba and Australia. Definition and description Cenotes are surface connections to subterranean water bodies. While the best-known cenotes are large open-water pools measuring tens of meters in diameter, such as those at Chiche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Choo-Ha
Choo-Ha, ''Tamcach-Ha'' and ''Multun-Ha'' are a series of small cenotes close to the Mayan site of Cobá in central Yucatán Peninsula The Yucatán Peninsula (, also , ; es, Península de Yucatán ) is a large peninsula in southeastern Mexico and adjacent portions of Belize and Guatemala. The peninsula extends towards the northeast, separating the Gulf of Mexico to the north .... All of them are accessible to the public for swimming. Choo-Ha has a small entrance of only about 3 by 4 meters. Fauna Small fish and turtles live in this cenote. Visitors must take a shower to clean themselves before swimming.

Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Sistema Dos Ojos
Dos Ojos (from Spanish meaning "Two Eyes"; officially Sistema Dos Ojos) is part of a flooded cave system located north of Tulum, on the Caribbean coast of the Yucatán Peninsula, in the state of Quintana Roo, Mexico. The exploration of Dos Ojos began in 1987 and still continues. The surveyed extent of the cave system is and there are 28 known sinkhole entrances, which are locally called cenotes. In January 2018, a connection was found between Sistema Dos Ojos and Sistema Sac Actun. The smaller Dos Ojos became a part of Sac Actun, making the Sistema Sac Actun the longest known underwater cave system in the world. 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. Dos Ojos contains the deepest known cave passage in Quintana Roo with of depth located at "The Pit" discovered in 1996 by cave explorers who came all the way from the ...

Sistema Nohoch Nah Chich
Sistema Nohoch Nah Chich (from Spanish and Yucatec Maya meaning "Giant Birdcage System"), is located south of Akumal in Tulum Municipality of Quintana Roo state, southeastern Mexico. It is part of the underwater cave systems. It is an extensive water filled cave system connected with the Caribbean Sea, fed via a coastal spring in a cenote with a variety of names, including ''Cenote Manati'', ''Cenote Tankah'', and ''Casa Cenote'' after a nearby restaurant. The explored cave system extends to approximately inland from the coast. Sistema Nohoch Nah Chich was discovered to be connected to the Sistema Sac Actun, making the Sac Actun the longest surveyed underwater cave system in the world. Exploration For more than ten years the system was extensively explored by dedicated cave divers starting from Cenote Nohoch Nah Chich. In 1987 Mike Madden of CEDAM International Dive Center established the CEDAM Cave Diving Team principally to conduct annual exploration projects to focu ...

Sistema Sac Actun
Sistema Sac Actun (from Spanish and Yucatec Maya meaning "White Cave System") is an underwater cave system situated along the Caribbean coast of the Yucatán Peninsula with passages to the north and west of the city of Tulum. Discovery of a connection to the Sistema Dos Ojos in 2018 made it the longest known underwater cave system. The remains of a mastodon and a human female that might be the oldest evidence of human habitation in this area to date have been found in the cave. History of exploration Exploration started from ''Gran Cenote'' west of Tulum. The whole of the explored cave system lies within the Municipality of Tulum (state of Quintana Roo). In early 2007, the underwater cave Sistema Nohoch Nah Chich was connected into and subsumed into Sac Actun making it the longest surveyed underwater cave system in the world. Sac Actun measured (after connecting ''Sistema Aktun Hu'' with in January 2011) and is as of May 2017 with an explored length of only surpassed by Si ...

Sistema Ox Bel Ha
Sistema Ox Bel Ha (from Mayan meaning "Three Paths of Water"; short Ox Bel Ha) is a cave system in Quintana Roo, Mexico. It is the 2nd longest explored underwater cave in the world and ranks fourth including dry caves. As of January 2022 the surveyed length is of underwater passages. There are more than 140 cenotes in the system. Discoveries The Naranjal subsystem is part of Sistema Ox Bel Ha. 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 away from the Jailhouse cenote entrance. The skeleton of a 44 to 50-year-old woman, ' (8,937±203 cal BP) was found at a location around away from the Jailhouse cenote entrance. The Muknal cave, part of the Naranjal subsystem, contained the remains of a 40 to 50-year-old man, the ''Muknal Grandfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quintana Roo
Quintana Roo ( , ), officially the Free and Sovereign State of Quintana Roo ( es, Estado Libre y Soberano de Quintana Roo), is one of the 31 states which, with Mexico City, constitute the 32 federal entities of Mexico. It is divided into 11 municipalities and its capital city is Chetumal. Quintana Roo is located on the eastern part of the Yucatán Peninsula and is bordered by the states of Campeche to the west and Yucatán to the northwest, and by the Orange Walk and Corozal districts of Belize, along with an offshore borderline with Belize District to the south. As Mexico's easternmost state, Quintana Roo has a coastline to the east with the Caribbean Sea and to the north with the Gulf of Mexico. The state previously covered and shared a small border with Guatemala in the southwest of the state. However, in 2013, Mexico's Supreme Court of Justice of the Nation resolved the boundary dispute between Quintana Roo, Campeche, and Yucatán stemming from the creation of the Calakm ...

Pond
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be ...

Water Table
The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as ...

Cave System
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganism ...
