Remember the saying that lightning never strikes in the same place twice? Forget that. A remarkable site at the mouth of the River Catatumbo, branching off Maracaibo Lake in western Venezuela, is the stage for an amazing lightshow on average 150 nights a year, totalling a million flashes annually. Oddly though, no thunder follows the lightning. The bizarre phenomenon is found nowhere else on Earth, and is thought to be the single biggest generator of ozone on the planet.

National Geographic did a documentary on the Crystal Caves. A bunch of scientists went down in there, figured out what makes it tick.
At some point in the future they will flood the cave again to prevent damage to the crystals.
