We got up around 6:30 after a long night of going to bed about 1 AM and getting lost on the way to camp. We all ate cereal and fruit, cleaned out our cabins and pitched our tents. We headed out to Wind Cave. It took about 45 minutes to get there.
At the Wind Cave we learned about how the cave was formed and we took about a hour and fifteen minute tour through the cave. We learned about a door that they used to have to use to get into the cave, the hole was about the size of a cowboy hat and was shaped like a hour glass. We entered through a revolving door that had a wind seal so they could control the temperature of the cave. The temperature stays at about 53 degrees. If they didn’t have the air seal on it, the temperature and moisture content of the cave would change, affecting the rock formations. While in the cave we found that it was very dark, cool and damp. The rocks were really layered and the cave looks like a sponge or Swiss cheese. The cave had Boxwork (it is like building a wall out of sugar and cement and sugar dissolves.) It is the only cave in the United States that has boxwork in it. The cave was lowered and they put concrete in it to have the tour. Connor and some of the others that are over 5’ 2” kept hitting their heads on the cave walls and nobody else had to worry about that.
After we left the cave we went to the park around wind cave to do an investigation. During our investigation we tried to figure out how the cave was formed and what kind of rock was making the cave. We found that there was limestone, shale, and sandstone making the cave. The shale is like clay and seals out water so it doesn’t sink in. The sandstone was like sand and soaked into the rock. We looked at the outcrop of the rock to find our data. We found that the rock was sedimentary because the rocks were layered and busted up. While we were taking our data we had to dodge the bison pies and the cactus. Dylan M got a high five from Mrs. Schoeneck after answering questions correctly.
After we got done with our investigation we went to Black Hills Geology Institute. There we found fossils of dinosaurs and different fossils and rocks. Neal Larson came and talked to us at the Institute. He showed us some of the dinosaurs that they are working on to go into the Institute. We learned about the different names of the dinosaurs and what they mean. Dinosaur means terrible lizard. Dinosaurs are very closely related to birds.
