Cayman Brac
Cayman Brac is an island that is part of the Cayman Islands. It lies in the Caribbean Sea about north-east of Grand Cayman and east of Little Cayman. It is about long, with an average width of . Its terrain is the most prominent of the three Cayman Islands due to " The Bluff", a limestone outcrop that rises steadily along the length of the island up to above sea level at the eastern end. The island is named after this prominent feature, as "brac" is a Gaelic name for a bluff. History Christopher Columbus sighted Cayman Brac and its sister island, Little Cayman, on 10 May 1503 when his ship was blown off course during a trip between Hispaniola and Panama. He named them "Las Tortugas" because of the many turtles he spotted on the islands. The Cayman Islands were renamed by Sir Francis Drake, who came upon the islands during a voyage in 1586. He used the word "Caymanas", taken from the Carib name for crocodiles after seeing many of the large crocodilians. Many people believ ...

Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Cyclura
''Cyclura'' is a genus of lizards in the family Iguanidae. Member species of this genus are commonly known as "cycluras" or more commonly as rock iguanas and only occur on islands in the West Indies. Rock iguanas have a high degree of endemism, with in most cases a single species or subspecies restricted to an individual island. Taxonomy The genus ''Cyclura'' was first circumscribed by Richard Harlan in 1825 to include two new species of lizard: ''C. carinata'' and ''C. teres''. ''C. teres'' eventually turned out to be a junior synonym of '' Ctenosaura acanthura''. In the 20th century there were eight recognised species of ''Cyclura'' and nine additional subspecies (one extinct) besides the nominotypical subspecies. Recently, certain subspecies were elevated to species status. Currently, there are ten species in this genus. Habitat Rock iguanas most often inhabit subtropical zones, of Caribbean island dry forest biomes. These landscapes are characterised by rocky outcrops, r ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Hiking
Hiking is a long, vigorous walk, usually on trails or footpaths in the countryside. Walking for pleasure developed in Europe during the eighteenth century.AMATO, JOSEPH A. "Mind over Foot: Romantic Walking and Rambling." In ''On Foot: A History of Walking'', 101-24. NYU Press, 2004. Accessed March 1, 2021. http://www.jstor.org/stable/j.ctt9qg056.7. Religious pilgrimages have existed much longer but they involve walking long distances for a spiritual purpose associated with specific religions. "Hiking" is the preferred term in Canada and the United States; the term "walking" is used in these regions for shorter, particularly urban walks. In the United Kingdom and the Republic of Ireland, the word "walking" describes all forms of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling , hillwalking, and fell walking (a term mostly used for hillwalking in northern England). The term bushwalking is end ...

Traditional Climbing
Traditional climbing (or Trad climbing) is a style of rock climbing in which the climber places all the necessary protection gear required to arrest any falls as they are climbing, and then removes it when the pitch is complete (often done by the second/follow-on climber). Traditional bolted aid climbing means the bolts were placed while on lead and/or with hand drills (the bolts tend to be much farther apart than for sport climbs). Traditional climbing carries a higher level of risk than bolted sport climbing, as the climber may not have placed the safety equipment correctly while trying to ascend the route; for some of the world's hardest climbs (e.g. '' Realization/Biographie''), there may not be sufficient cracks or features in the rock that can accept protection gear, and the climb can only be safely attempted by bolting as a sport climb. Overview Characterizing climbing as ''traditional'' distinguishes it from bolted climbing—either trad bolted or sport climbing ...

Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1932 Cuba Hurricane
The 1932 Cuba hurricane, known also as the Hurricane of Santa Cruz del Sur or the 1932 Camagüey hurricane,Millás, p. 1 was the deadliest and one of the most intense tropical cyclones on record to have made landfall in Cuba. It is the only Category 5 Atlantic hurricane ever recorded in November. The cyclone had a path through the Caribbean Sea atypical to most hurricanes developing late in the Atlantic hurricane season. The storm's strong winds, storm surge, and rain devastated an extensive portion of central and eastern Cuba, where the storm was considered the worst natural disaster of the 20th century. Though the effects from the hurricane were concentrated primarily on Cuba, significant effects were also felt in the Cayman Islands and the Bahamas, with lesser effects felt elsewhere. The tropical depression that would later develop into the destructive hurricane was first located east of the Lesser Antilles on October 30, and tracked westward into the Caribbean ...

Caving
Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.) The challenges involved in caving vary according to the cave being visited; in addition to the total absence of light beyond the entrance, negotiating pitches, squeezes, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Western Hemisphere
The Western Hemisphere is the half of the planet Earth that lies west of the prime meridian (which crosses Greenwich, London, United Kingdom) and east of the antimeridian. The other half is called the Eastern Hemisphere. Politically, the term Western Hemisphere is often used as a metonymy for the Americas, even though geographically the hemisphere also includes parts of other continents. . Geography The Western Hemisphere consists of the , excluding some of the |
Cuban Navy
The Cuban Revolutionary Navy ( es, Marina de Guerra Revolucionaria) is the navy of Cuba. History The Constitutional Navy of Cuba was the navy of Cuba that existed prior to 1959. During World War II, it sank the German submarine ''U-176'' on 15 May 1943. During the Cold War, the Cuban Navy successfully captured the freighters Leyla Express and Johnny Express, both vessels blamed for CIA-related activities against Cuba. In 1988, the Cuban Navy boasted 12,000 men, three submarines, two modern guided-missile frigates, one intelligence vessel, and a large number of patrol craft and minesweepers. However, most of the Soviet-made vessels have been decommissioned or sunk to make reefs. By 2007, the Cuban Navy was assessed as being 3,000 strong (including up to 550+ Navy Infantry) by the IISS with six Osa-II and one . The Cuban Navy also includes a small marine battalion called the ''Desembarco de Granma''. It once numbered 550 men though its present size is not known. Cuban N ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...
