Chiquibul Cave System
The Chiquibul Cave System is one of the largest and best-known cave systems in Central America. It consists of four distinct caves along the course of the Chiquibul River; Actun Kabal, Actun Tun Kul (Tunkul) and Cebada Cave in Belize, and Xibalba in Guatemala, as well as several other smaller associated caves. Included within the cave system are two of the largest caverns in the world. Actun Kabal (Kabal Group) This upper section of the Chiquibul Cave System has over 12 km of mapped passages with a depth of -95 m. Included is Chiquibul Chamber, at 250 m by 150 m one of the world's largest caverns. Actun Tun Kul Tun Kul ("stone drum") includes Belize Chamber - with dimensions of 300 m by 150 m by 65 m, it is one of the largest natural caverns in the world. Tun Kul was connected with Cebada Cave in 1999 resulting in a 39 km long cave. Cebada Cave Cebada Cave and Tun Kul were linked in 1999; at 39 km it is the longest cave in Belize. Xibalba This downstream section of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave
Caves or caverns are natural voids under the Earth's Planetary surface, surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). 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, ''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, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sedime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Belize
Belize is a country on the north-eastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a maritime boundary with Honduras to the southeast. Part of the Caribbean region, Belize is a member of the Caribbean Community (CARICOM) and the Commonwealth Caribbean, the historical British West Indies. The Maya civilization spread into the area of Belize between 1500 BCE and 300 CE and flourished until about 1200. European contact began in 1502–04 when Christopher Columbus sailed along the Gulf of Honduras. European exploration was begun by English settlers in 1638. Spanish Empire, Spain and Kingdom of Great Britain, Britain both laid claim to the land until Britain defeated the Spanish in the Battle of St. George's Caye (1798). It became British Honduras, a British colony in 1840, and a Crown colony in 1862. Belize achieved its independence from the United Kingdom on 21 September ...

Guatemala
Guatemala, officially the Republic of Guatemala, is a country in Central America. It is bordered to the north and west by Mexico, to the northeast by Belize, to the east by Honduras, and to the southeast by El Salvador. It is hydrologically bordered to the south by the Pacific Ocean and to the northeast by the Gulf of Honduras. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica; in the 16th century, most of this was Spanish conquest of Guatemala, conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence from Spain and Mexico in 1821. From 1823 to 1841, it was part of the Federal Republic of Central America. For the latter half of the 19th century, Guatemala suffered instability and civil strife. From the early 20th century, it was ruled by a series of dictators backed by the United States. In 1944, authoritarian leader Jorge Ubico was overthrown by a pro-democratic m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cave Survey
A cave survey is a map of all or part of a cave system, which may be produced to meet differing standards of accuracy depending on the cave conditions and equipment available underground. Cave surveying and cartography, i.e. the creation of an accurate, detailed map, is one of the most common technical activities undertaken within a cave and is a fundamental part of speleology. Surveys can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for other areas of scientific study and assist visitors with route-finding. Traditionally, cave surveys are produced in two-dimensional form due to the confines of print, but given the three-dimensional environment inside a cave, modern techniques using computer aided design are increasingly used to allow a more realistic representation of a cave system. History The first known plan of a cave dates from 1546, and was of a man-made cavern in tufa called the Stufe di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illegal Logging
Illegal logging is the harvest, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger-scale environmental crises such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through smuggling, fraudulent declaration to customs); the tax avoidance, avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and ...
