Luquillo Mountains, Puerto Rico
Published February 4, 2008
The Luquillo Mountains are located in the northeastern portion of Puerto Rico, and they rise to elevations of 1,075 meters (about 3,527 feet). Higher elevations receive more rainfall than lower elevations, leading to subtropical forest types in the lowlands and high-mountain forest types near the summits. This astronaut photograph, taken during the rainy season, illustrates the rich vegetation on the mountains.
