Geode crystal.

Stand Inside World's Largest Geode

Field review by the editors.

Put-in-Bay, Ohio

How does a winery survive Prohibition? By giving tours of its giant geode! That's what Heineman Winery did, and continues to do, with "Crystal Cave," which in fact is the World's Largest Geode. Buried 40 feet under the winery, it was fortuitously discovered in 1897 (23 years before Prohibition) by winery well-diggers. Its chamber walls are covered in blueish crystals of celestite, up to a foot-and-a-half long.
