Wind Cave National Park includes scenic areas like this. The caves are below this ground.And of course, there are many buffalo within the park!This is the original natural entrance to the cave.Wind Cave got its name because of the wind that blows out of the natural entrance. The park ranger demonstrates the wind here. Depending on air pressure inside and outside the cave, the wind also blows into the cave.The stairs down the cave were narrow and steep.There are interesting holes and formations throughout the cave.Wind Cave is most famous for its boxwork formation. The origin of boxwork remains one of the biggest mysteries of Wind Cave. Boxwork is made of thin blades of calcite that project from cave walls and ceilings, forming a honeycomb pattern. The fins intersect one another at various angles, forming “boxes” on all cave surfaces.This is the largest room in the cave that we visited. It is 200 feet underground. The ranger demonstrated total darkness by turning off all the lights for a couple minutes. It was kind of disorienting. Excellent tour.
