Geography
Dominica is an island nation and borderless country in the Caribbean Sea, the largest and most northerly of the Windward Islands. The island faces the Atlantic Ocean to the east and the Caribbean Sea to the west. Its nearest neighbours are the French islands of Guadeloupe, some 48 km north, and Martinique, about 40 km south. Oblong-shaped and slightly smaller than New York City, Dominica is 750 sq km in area, 47 km in length, and 29 km in width. Roseau, the nation's capital and major port, is favourably situated on the sheltered, south-western coast.
It is said that when his royal sponsors asked Christopher Columbus to describe this island in the New World, he crumbled a piece of parchment roughly and threw it on the table. "This", Columbus explained, "is what Dominica looks like - completely covered with mountains with nary a flat spot".
Geographically, Dominica is distinctive in many ways. The country has one of the most rugged landscapes in the Caribbean, covered by a largely unexploited, multi-layered rain forest. It is also among the earth's most rain-drenched lands, and the water runoff forms cascading rivers and natural pools. The island, home to rare species of wildlife, is considered by many as a beautiful, unspoiled tropical preserve. According to a popular West Indian belief, Dominica is the only New World territory that Columbus would still recognise.
Terrain
Geologically, Dominica is part of the rugged Lesser Antilles volcanic arc. The country's central spine, a northwest-southeast axis of steep volcanic slopes and deep gorges, generally varies in elevation from 300 metres to 1,400 metres above sea level. Several east-west trending mountain spurs extend to the narrow coastal plain, which is studded with sea cliffs and has level stretches no wider than 2,000 metres. The highest peak is Morne Diablotins, at 1,447 metres; Morne Trois Pitons, with an elevation of 1,423 metres, lies farther south and is the site of the national park.
Dominica's rugged surface is marked by its volcanic past. Rock formations are mainly volcanic andesite and rhyolite, with fallen boulders and sharp-edged protrusions peppering slope bases. The light- to dark-hued clayey and sandy soils, derived from the rocks and decomposed vegetation, are generally fertile and porous. Only a few interior valleys and coastal strips are flat enough for soil accumulations of consequence, however. Although scores of mostly mild seismic shocks were recorded in 1986, volcanic eruptions ceased thousands of years ago. Sulfuric springs and steam vents, largely concentrated in the central and southern parts of the island, remain active, however. One of the largest springs, Boiling Lake, is located in the national park.
Water
Dominica is water-rich with swift-flowing highland streams, which cascade into deep gorges and form natural pools and crater lakes. The streams are not navigable, but many are sources of hydroelectric power. Trafalgar Falls, located near the national park, is one of the most spectacular sites on the island. The principal rivers flowing westward into the Caribbean are the Layou and the Roseau, and the major one emptying eastward into the Atlantic is the Toulaman. The largest crater lake, called Boeri, is located in the national park.
Disputes
The Commonwealth of Dominica is engaged in a long-running dispute with Venezuela over Venezuela's territorial claims to the sea surrounding Isla Aves (Bird Island), a tiny islet located 70 miles (110 km) west of the island of Dominica.
