Wind Cave is one of the oldest, longest and most complex three dimensional caves in the world. At over 150 miles, is the fourth longest cave in the world.  WIND CAVE: ONE PARK, TWO WORLDS takes viewers on an unforgettable journey into two vastly different landscapes of uncompromising beauty: the prairie on the surface and cave below the ground.  This is the same video shown in the Visitor Center and is approximately 20 minutes long.  DVD only (Great Divide Pictures, 2001)
