I drove all the way down to Wind Cave National Park, which is south of Custer State Park, since I didn’t feel like seeing another museum and a cave visit was on my list for this year. This is the 4th longest cave in the world and is very complex. It’s not straight but has many tunnels and paths along side each other, like zigzag lines. It is drier than most caves, so it doesn’t have the typical stalactites and stalagmites in it. It does have rare boxwork and frostwork on the ceilings and walls. The CCC built the visitor center, the many stairs where visitors are allowed to go, with a ranger for a cost, and the elevator shaft, used for exits and some tours’ entrances.
