There are three important mountain ranges in Cuba--the Sierra de los Organos, the Sierra de Trinidad and the Sierra Maestra. All of these mountains have special features that make them different from each other.  The longest river The Cauto which flows west for about 230 miles runs into the Gulf of Guacanayabo. Cuba's terrain is not flat and smooth but in fact very rugged and is the reasoning why the 600 rivers of Cuba flow into waterfalls. While researching Cuba we found that it was the Caribbean plate that Cuba was found on but it has remained relatively inactive for quite sometime. "The Cuban arc terrain holds a wealth of information that tells of a complex tectonic, metamorphic and magmatic history dates back to the Juassic" (Pindel, 2003).  Geographically, though, Cuba has been isolated from the Caribbean plate since about the Eocene. It was determined however that since the geology of the Cuban arc terrain is so similar to the other Caribbean terrain that it was part or has been a part of the Caribbean Plate since the Paleocene. This is truly amazing in the fact that the more we can learn about the plates and formations of the lands that lie on them the more we can determine the age of the different countries and maybe even prove the theory that at one time all the continents were once connected. The biggest issue that we ran into when researching the plate tectonics of Cuba was that most of the papers were written in Russian and our libraries held very little if any information on Cuban history. It was the abstracts of the V Cuban Geological Congress conference that gave us this little information. No matter how little we receive it still is enough to give us food for thought and continue our exploration on the Caribbean as well as the Pacific plate for information on the formation of Cuba as well as the rest of the Caribbean and Southern Pacific.
