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 39km long cave. Cebada Cave Cebada Cave and Tun Kul were linked in 1999; at 39 km it is the longest cave in Belize.

Cave
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, microorgani ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central 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. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belize
Belize (; bzj, Bileez) is a Caribbean and Central American country on the northeastern 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 water boundary with Honduras to the southeast. It has an area of and a population of 441,471 (2022). Its mainland is about long and wide. It is the least populated and least densely populated country in Central America. Its population growth rate of 1.87% per year (2018 estimate) is the second-highest in the region and one of the highest in the Western Hemisphere. Its capital is Belmopan, and its largest city is the namesake city of Belize City. Belize is often thought of as a Caribbean country in Central America because it has a history similar to that of English-speaking Caribbean nations. Indeed, Belize’s institutions and official language reflect its history as a British colony. The Maya civilization spread into the area of Beli ...

Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Speleological Society
The National Speleological Society (NSS) is an organization formed in 1941 to advance the exploration, conservation, study, and understanding of caves in the United States. Originally headquartered in Washington D.C., its current offices are in Huntsville, Alabama. The organization engages in the research and scientific study, restoration, exploration, and protection of caves. It has more than 10,000 members in more than 250 grottos. History The Speleological Society of the District of Columbia (SSDC) was formed on May 6, 1939 by Bill Stephenson. In the fall of 1940, the officers of the SSDC drafted a proposed constitution that would transform the SSDC into the National Speleological Society. On January 24, 1941, Stephenson sent a letter to all members of the SSDC announcing that "on January 1 the Society was reorganized as a national organization." The New England Grotto was the first NSS Grotto. It was chartered in 1941 with Clay Perry as president and Ned Anderson as vice pr ...

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 crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the 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 demand for pasture for ...
