[Rockhounds] Climb inside The World's Largest Geode

[Kreigh Tomaszewski]

If you can figure out which one it is...

The World's Largest Geode Formed When the Mediterranean Sea Disappeared,
New Study Reveals
Most geodes can fit in the palm of your hand. The Pulpí Geode can fit your
entire family inside it.

In an abandoned mine in southern Spain, there is a room of pure crystal.

To get there, you'll have to descend deep into tunnels, climb a ladder into
an inconspicuous hole in the rocks and squeeze through a jagged tube of
gypsum crystals barely wide enough for one person. If you make it that far,
you'll be standing inside the world's largest geode: the Pulpí Geode, a
390-cubic-foot (11 cubic meters) cavity about the size of a cement mixer
drum, studded with crystals as clear as ice and sharp as spears on every
surface.

Crystal Cave - The World's Largest Geode
See celestine crystals up to 3 feet in width!

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.

Owned and operated by Heineman Winery, Crystal Cave helped save the
family-run winery from demise during Prohibition. Tours of the cave helped
pay the bills, while other wineries on the island closed.
