Grutas del Águila (Eagle Cave) is a single huge chamber with a surface of 10,000m². It is entered from the surface down a 20m deep staircase, the rest of the tour is an almost level round course on the floor of this huge chamber.
The cave was disocvered on Christmas Eve 1963 by five boys, the children of local farm workers. They saw a column of "smoke" on this cold day, actually it was the condensing humidity from the warm and humid cave air emerging through the cave entrance. So they were able to locate the cave entrance in Cerro de Romperropas. When they reached the entrance, they decided to explore the cave and discovered the huge chmaber. A phantastic adventure and they became famous for discovering the cave, but actually exactly the kind of stunt we strongly discourage on this website. They went into the cave with a single flashlight and some rope, no other preparations or equipment. As a result they got lost for five hours inside this extremely easy cave. And this cave is just a single huge chamber, would they have survived if the cave was a labyrinthic cave system?
This cave is noted for an abundance of speleothems including stalactites, stalagmites, pillars, rimstone pools, and helictites. A specialty are so-called cave corals, which are actually fine calcite crystals which formed on stalagamites and cover them lookong like fur. There are moonmilk, popcorn, anthodite and crust speleothems found in diferent parts of the cave. They are probably a result of evaporative processes, according to Hill and Forti (1997).
This cave is visited by many visitors, which normally influences the atmospheric conditions inside a cave radically. Many painted caves had to be closed because of this. In order to decide how much cave temperature depends on such influences, to decide how reliable temperature measurement on speleothems are, a team of cave scientists evaluated temperature measurements of this cave. The result was interesting: the cave was almost unchanged by the huge amount of visitors, because the warmth could spread out inside the huge chamber. The makes measurements of palaeoclimate form speleothems of this cave very reliable.
