Baoruco Mountain Range
The Baoruco Mountain Range—Sierra de Baoruco (or Sierra de Bahoruco) is a mountain range located in the far southwestern region of the Dominican Republic. It is within Pedernales, Independencia, Barahona, and Baoruco Provinces .
The range is a continuation of the Massif de la Selle in Haiti.
Part of the area is protected within the Sierra de Bahoruco National Park (Parque Nacional Sierra de Bahoruco), also a Biosphere reserve.
The Sierra de Baoruco are noted for the blue colored concretions called larimar, which formed in the range's volcanic vesicles.
Larimar is the Dominican name for a mineral assemblage of acidic silicate hydrates of calcium and sodium. Larimar is a specific type of pectolite (occasionally as ratholite), a pyroxenoid mineral.
