National Geographic Into the Lost Crystal Caves Explores Superman’s Fortress of Solitude

If you thought that Superman’s Fortress of Solitude could only be found in the comic books , think again. National Geographic will be premiering a new show on Sunday called ‘Into the Lost Crystal Caves.’ The show will take viewers inside an awesome cave that features crystals that range upwards of 26 feet long and weigh 55 tons. However Superman and Lois Lane won’t actually be there. Humans can only withstand being in the caves no longer than 15 minutes or they will die because of the super hot temperatures.  I guess that would be our own equivalent to Kryptonite.  Into the Lost Crystal Caves premieres on Sunday Oct 10th an 8pm on the National Geographic Channel.
