Geography of Haiti - Relief

Relief

• 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 Ile d'Haiti's) longest river, the Riviere l'Artibonite whose watershed 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 Gulf of Gonâve. The river is navigable for a distance by barge. The eastern and central region of the island is a large elevated plateau.

• 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 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, whose most northwestern part merges with the Massif du Nord.

• 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 (also known as Etang Saumatre). 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).
