In Podcast #14 the Virginia Trekkers went to Luray Caverns in the Valley and Ridge region of Virginia.  Find out how these amazing caverns formed, learn the difference between stalactites and stalagmites, discover why the rock formations are different colors, and strain your eyes as you try to see us in the darkness (our video cameras didn’t do too well in the dark).  Come on, let’s go trekkin’!

Luray caverns was the site of the first air-conditioned home in America.  In 1901 a house called “Limair” was built over Luray Caverns.  It was kept a comfortable 70ºF even on the hottest summer days by using pipes and fans to blow cool air from the caverns into the house.  The reason this worked is because the air inside Luray caverns stays at a constant temperature of 54ºF no matter how hot or cold it is outside.  This is because of the insulation from all the rocks and earth surrounding it.
