Mountains, Coastal Plains and River Valleys of Haiti
Haiti is situated on the western part of Hispaniola, the second largest island in the Greater Antilles. Haiti is the third largest country in the Caribbean behind Cuba and the Dominican Republic (the latter shares a 360 kilometer (224 mi) border with Haiti). Haiti’s terrain consists mainly of rugged mountains interspersed with small coastal plains and river valleys.
The northern region consists of the Massif du Nord (Northern Massif) and the Plaine du Nord (Northern Plain). The Massif du Nord is an extension of the Cordillera Central in the Dominican Republic. It begins at Haiti’s eastern border, north of the Guayamouc River, and extends to the northwest through the northern peninsula. The lowlands of the Plaine du Nord lie along the northern border with the Dominican Republic, between the Massif du Nord and the North Atlantic Ocean.
The central region consists of two plains and two sets of mountain ranges. The Plateau Central (Central Plateau) extends along both sides of the Guayamouc River, south of the Massif du Nord. It runs from the southeast to the northwest. To the southwest of the Plateau Central are the Montagnes Noires (Black Mountains) whose most northwestern part merges with the Massif du Nord. Its westernmost point is known as Cap Carcasse.
The southern region consists of the Plaine du Cul-de-Sac (the southeast) and the mountainous southern peninsula (also known as the Tiburon Peninsula). The Plaine du Cul-de-Sac is a natural depression which harbors the country’s saline lakes, such as Trou Caïman and Haiti’s largest lake, Lac Azuei.
The Chaîne de la Selle mountain range, an extension of the southern mountain chain of the Dominican Republic (the Sierra de Baoruco), extends from the Massif de la Selle in the east to the Massif de la Hotte in the west. This mountain range harbors Pic la Selle, the highest point in Haiti at 2,680 metres (8,793 ft).
The country’s most important valley in terms of crops is the Plaine de l’Artibonite, which is oriented south of the Montagnes Noires. This region supports the country’s (also Hispaniola’s) longest river, the Riviere l’Artibonite which begins in the western region of the Dominican Republic and continues most of its length through central Haiti and onward where it empties into the Golfe de la Gonâve. The eastern and central region of the island is a large elevated plateau.
