- Yucatán Peninsula
The Yucatán Peninsula, in Southeastern
Mexico, separates the Caribbean Seafrom the Gulf of Mexico. It also has a costline on the Yucatán Channel. The peninsulalies east of the Isthmus of Tehuantepec, a northwestern geographic partition separating the region of Central Americafrom the rest of North America.
The peninsula comprises the Mexican states of
Yucatán, Campeche, and Quintana Roo; the northern part of the nation of Belize; and Guatemala's northern department of El Petén. Mexican states situated on the isthmus to the west of the peninsula include Chiapasand Tabascoand is directly within the hurricane belt.
The peninsula is the surface exposed portion of the larger Yucatán Platform, all of which is composed of carbonate and soluble rocks, being mostly
limestonealthough dolomite and evaporites are also present at various depths. The whole of the Yucatán peninsula is a karstlandscape. Sinkholes, locally called cenotesare widespread in the northern lowlands.
This peninsula is separated from
Cubaby the Yucatán Channel, the widest connection of the Gulf of Mexicowith the Caribbean Seaand the rest of the Atlantic Ocean.
According to the
Alvarez hypothesis, the Yucatán Peninsula was the site of an ancient asteroidimpact which is likely to have caused the mass extinctionat the end of the Cretaceous Period. The crater is centered off the north coast of the modern town of Chicxulub (see Chicxulub Crater). The now-famous "Ring of Cenotes" (visible in NASAimagery) outlines one of the shock-waves from this impact event in the rock of ~65 millions years of age, which lies more than 1 km below the modern ground surface, with the rock above the impact strata all being younger in age. The mechanism by which this deeply buried impact crater is observed and defined through mass spectrometers and digital radar imagers.
Short and tall dry tropical jungles are the predominant natural vegetation types of the Yucatan peninsula.
The boundaries between northern Guatemala (El Petén), Mexico (
Campecheand Quintana Roo), and western Belizeare still occupied by the largest continuous tracts of tropical rainforestin Central America. However, these forests are suffering extensive deforestation.
There is a popular myth that the name Yucatán comes from the Yucatec Maya phrase for "listen how they speak," or "I don't understand your words" -- supposedly said by contact period Maya when the first Spanish explorers asked what the area was called. The proper derivation of the word Yucatán is widely debated. However, it is also claimed that the actual source of the name "Yucatan" is the Nahuatl (Aztec) word Yokatlān, "place of richness."
The Yucatán Peninsula comprises a significant proportion of the ancient Maya Lowlands (although the Maya culture extended south of the Yucatán peninsula, through present Guatemala and into Honduras and highland Chiapas). There are many Maya archaeological sites throughout the peninsula; some of the better-known are
Chichen Itza, Tulumand Uxmal. [http://en.wikipedia.org/wiki/Category:Maya_sites] , [http://mayaruins.com/yucmap.html] Indigenous Maya and Mestizos of partial Maya descent still make up a sizable portion of the region's population, and Mayan languagesare still widely spoken there.
In the late historic and early modern eras, the Yucatán Peninsula was largely a cattle ranching, logging,
chicleand henequenproduction area. Since the 1970s (and the fall of the world henequen and chicle markets due to the advent of synthetic substitutes), the Yucatán Peninsula has reoriented its economy towards tourism, especially in the Mexican state of Quintana Roo. Once a small fishing village, Cancúnin the northeast of the peninsula has grown into a thriving city. The Riviera Maya, which stretches along the east coast of the peninsula between Cancúnand Tulum, currently has more than 50,000 beds and is visited by many thousands of tourists every year.
Like much of the
Caribbean, the peninsula lies within the Atlantic Hurricane Belt, and with its almost uniformly flat terrain it is vulnerable to these large storms coming from the east. The 2005 Atlantic Hurricane Seasonwas a particularly bad season for Mexico's tourism industry, with two forceful category 5 storms hitting, Hurricane Emily and Hurricane Wilma. The 2006 Atlantic Hurricane Seasonwas a typical year which left the Yucatán untouched, but in the 2007 Atlantic Hurricane season Yucatán was hit by the Hurricane Dean(also a category 5 storm), nevertheless Dean left little damage on the peninsula despite heavy localized flooding.
Strong storms called nortes can quickly descend on the Yucatán Peninsula any time of year. Although these storms pummel the area with heavy rains and high winds, they tend to be short-lived, clearing after about an hour. The average percentage of days with rain per month ranges from a monthly low of 7% in April to a high of 25% in October. Breezes can have a cooling effect,
humidityis generally high, particularly in the remaining rainforest areas.
