Central America has some of the most interesting ancient american history hidden deep within the jungles and even deeper within the caves of these sacred dwellings. Researchers and scientists have been mapping the caves for over the past few decades now and  continue to find new passages and artifacts.  These caves are protected under many covenants and it is important for scientists and researchers to continue to put the pieces together in the pursuit of understanding how the lost civilizations lived and how they disappeared.  The expeditions are on going and the re-survey is important to ensure accuracy and to gain attendance into the world that the lost civilizations considered, a gateway to another dimension.
