I've taken a hammer to quite a few geodes in my life, but I had never seen anything like this underground geode on South Bass Island in Lake Erie.
Discovered in 1897 when islanders were trying to dig a well, this geode is filled with massive celestite crystals comprised of Strontium Sulfate (SrSO4).
 |
This geode has room for over a dozen people |
 |
Surrounded by crystals! |
The geode/cave is privately owned
and is called the
Crystal Cave.
 |
Crystals up close -- each crystal has 14 faces |
 |
This is the largest single crystal in the cave -- it weighs nearly 200 pounds |
These are the largest known celestite crystals in the world.
