Baoruco Mountain Range
The Bahoruco Mountain Range—Sierra de Bahoruco (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 Bahoruco 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. Etymology. Granberry and Vescelius (2004) suggest a Macoris etymology for the name "Bahoruco", comparing it with "baho-ro-eku" 'within the jungle' in the purportedly related Warao language  of the Orinoco Delta. Larimar. The Sierra de Bahoruco 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.
