The Great Maya Aquifer Project (GAM) was founded by National Geographic Society Explorer, Guillermo de Anda Ph.D, who, together with an interdisciplinary team, works to explore, understand and protect the aquifer of the Yucatan Peninsula. This is one of the largest and most complex aquifers in the world. It connects various delicate ecosystems in the region, providing almost all the fresh water available to its inhabitants. Moreover, the underground cave systems preserve extensive deposits of archaeological and paleontological materials that tells us the story of the first settlers of the American Continent. Likewise, the hydrogeological information of these systems is helping to understand more about the formation of our planet. For more information:
