Hispaniola - Geography

Geography

Hispaniola is the second-largest island in the Caribbean (after Cuba), with an area of 76,480 square kilometers (29,530 sq mi). Haiti has 10,620 square miles (27,500 km2) (almost 36% of the area); the Dominican Republic 18,704 square miles (48,440 km2)(over 64% of the area).

The island of Cuba lies 80 kilometers (50 mi) to the northwest across the Windward Passage; to the southwest lies Jamaica, separated by the Jamaica Channel. Puerto Rico lies east of Hispaniola across the Mona Passage. The Bahamas and Turks and Caicos Islands lie to the north. Its westernmost point is known as Cap Carcasse.

Cuba, Hispaniola, Jamaica, and Puerto Rico are collectively known as the Greater Antilles. The Greater Antilles are made up of continental rock, as distinct from the Lesser Antilles, which are mostly young volcanic or coral islands.

The island has five major mountain ranges: The Central Range, known in the Dominican Republic as the Cordillera Central, spans the central part of the island, extending from the south coast of the Dominican Republic into northwestern Haiti, where it is known as the Massif du Nord. This mountain range boasts the highest peak in the Antilles, Pico Duarte at 3,087 meters (10,128 ft) above sea level. The Cordillera Septentrional runs parallel to the Central Range across the northern end of the Dominican Republic, extending into the Atlantic Ocean as the Samaná Peninsula. The Cordillera Central and Cordillera Septentrional are separated by the lowlands of the Cibao Valley and the Atlantic coastal plains, which extend westward into Haiti as the Plaine du Nord (Northern Plain). The lowest of the ranges is the Cordillera Oriental, in the eastern part of the country.

The Sierra de Neiba rises in the southwest of the Dominican Republic, and continues northwest into Haiti, parallel to the Cordillera Central, as the Montagnes Noires, Chaîne des Matheux and the Montagnes du Trou d'Eau. The Plateau Central lies between the Massif du Nord and the Montagnes Noires, and the Plaine de l'Artibonite lies between the Montagnes Noires and the Chaîne des Matheux, opening westward toward the Gulf of Gonâve, the largest gulf of the Antilles.

The southern range begins in the southwestern most Dominican Republic as the Sierra de Bahoruco, and extends west into Haiti as the Massif de la Selle and the Massif de la Hotte, which form the mountainous spine of Haiti's southern peninsula. Pic de la Selle is the highest peak in the southern range, the third highest peak in the Antilles and consequently the highest point in Haiti, at 2,680 meters (8,790 ft) above sea level. A depression runs parallel to the southern range, between the southern range and the Chaîne des Matheux-Sierra de Neiba. It is known as the Plaine du Cul-de-Sac in Haiti, and Haiti's capital Port-au-Prince lies at its western end. The depression is home to a chain of salt lakes, including Lake Azuei in Haiti and Lake Enriquillo in the Dominican Republic.
