Dominica is an island in the Caribbean Sea, located about halfway between Puerto Rico and Trinidad and Tobago. Its coordinates are 15 25 N, 61 20 W. The island is roughly four times the size of Washington, DC (in area, not population). The island's climate is tropical, moderated by northeast trade winds and heavy rainfall. The interior features rugged mountains of volcanic origin. Volcanism is still quite evident on the island, the most popular examples being Dominica's boiling lake and "valley of desolation." The boiling lake (the world's second largest) is within a crater and is fed by a waterfall - the boiling is believed to be caused by the heat of a magma chamber beneath the lake.
