I am going to cheat and use the national park website information to tell you about Wind Cave National Park. I am just too busy having fun to type it all up myself. Here is the national park information: “Wind Cave National Park includes one of the world's longest and most complex caves and 28,295 acres of mixed-grass prairie, ponderosa pine forest, and associated wildlife are the main features of the park. The cave is well known for its outstanding display of boxwork, an unusual cave formation composed of thin calcite fins resembling honeycombs. The park's mixed-grass prairie is one of the few remaining and is home to native wildlife such as bison, elk, pronghorn, mule deer, coyotes, and prairie dogs. Wind Cave has always been a world class natural resource. However, it was not until explorers first entered, and then continued to push further underground, that the significance of Wind Cave began to be realized. When most people think about the importance of Wind Cave they tend to dwell on boxwork and the cave's vast length. Over many years of exploration and mapping, Wind Cave has grown to be one of the world's largest known caves. Currently over 134.16 miles of passages have been mapped in Wind Cave. This places Wind Cave as the third longest cave in the United States and fourth longest cave in the world.”
We loved the boxwork all over the cave. In fact, we ended up taking two tours into the cave to see as much as we could. We went up and down over 400 steps and went as deep as 250 feet underground. Both tours were exceptionally fun!
