The next morning we went to see the Jewel caves which was about an hour’s drive from Custer State park. It is the second-longest cave system in the world with 160 miles of explored passageways. The cave got its name from the dazzling calcite crystals that illuminate the underground and lighted walkways of the cave. We took the scenic tour which was of 1 ½ hrs duration. The tour guide took us down to the cave in an elevator and down several steps along a ½ mile loop.
We saw many chambers decorated with calcite crystals and other speleothems including stalactites, stalagmites, draperies, frostwork, flowstone, boxwork and hydromagnesite balloons.
The cave is an important hibernaculum for several species of bats. At one point, the guide asked us to stand together and then he put out all the lights inside of the cavern. It was quite exhilarating to be in total darkness.
This was one of the most fascinating cave tour I have ever had.
From here we headed towards the mystery spot Cosmos about which I have already written…
After the magical experience of Cosmos we drove towards Badlands national Park.
