World's Largest Geode
(taken from the Heineman's Winery website)
Discovered by workers in 1897 while digging a well for the winery 40 feet above, Crystal Cave is the world's largest geode. The walls of this cave are covered in strontium sulfate, a blueish mineral called celestite. These crystals range from 8 to 18 inches long. The original cave was much smaller than what appears today, as crystals were harvested and sold for the manufacturing of fireworks.
