From here, the cave system spans approximately 3 miles with stalactites, stalagmites, jarring boulders and fresh water streams from ankle to waist deep.The cavern ends with the main chamber where the calcified to sparkling crystalized remains of the “Crystal Maiden” lays, believed to be the skeleton frame of a young woman who was sacrificed in a bloodletting ceremony to the “gods”.
