Just outside of Hot Springs, South Dakota, we found one of the largest/longest caves in the world. Lincoln and I ventured into a cave for the first time, and it was spectacular. We went down 300 steps, over 200 feet under the earth.
1. Pictures from inside the cave highlighting the boxwork and popcorn calcium deposits inside the cave. The boxwork is an incredible product if erosion, and Wind Cave has 95% of the world's boxwork.
2. Lincoln near the park sign--it was a cool morning and actually warmer inside the cave.
3. Mr. Cool and Lincoln wait by the elevator--they don't make you climb out!
4. We enjoy our first cave!
