Sierra Maestra : ウィキペディア英語版 | Sierra Maestra
Sierra Maestra is a mountain range that runs westward across the south of the old Oriente Province from what is now Guantánamo Province to Niquero〔 (Niquero on guije.com )〕 in southeast Cuba, rising abruptly from the coast. Some view it as a series of connecting ranges (Vela, Santa Catalina, Quemado Grande, Daña Mariana),〔 (Guantánamo on guije.com )〕 which joins with others extending to the west.〔〔 (Caney on guije.com )〕〔 (Bayamo on guije.com )〕〔 (Cobre on guije.com )〕〔 (Manzanillo on guije.com )〕 The Sierra Maestra is the highest system of Cuba. It is rich in minerals, especially copper, manganese, chromium, and iron. At 1,974 m (6,476 ft), Pico Turquino is the range's highest point. ==Orography== Cuba rides on a separate tectonic plate, which originally was in the Pacific Ocean but (after crossing between the then separated Americas) crashed into Florida. This along with several other violent events (including volcanic activity, the crash of the comet Chicxulub, and earthquakes the Sierra Maestra is immediately north of the Bartlett Deep, or Cayman Trench on the main Caribbean Plate) fractured huge slabs of rocks. Enormous tsunamis presumably from the volcanoes on the Canary Islands carved great steps on the coast. All this caused emergence of these mountains in a complex process that included lifting up of now cave-ridden calcareous deposits, and the development of the Bartlett Deep or Cayman Trough. Originally heavily forested and divided by deep river valleys, volcanic dykes, and impassable karst areas, its steep valleys and abrupt fault lines make it an ideal terrain for rebellion.
