I went on the cave tour for $10. A prospector named Lehman settled in the area; he decided it was more profitable to start a ranch, and sell food to the other miners. There are still some fruit trees planted by Mr. Lehman at the visitor center, and you’re free to pick any fruit. Anyways, Lehman one day stumbled upon the entrance to this cave, and being a miner, he was definitely equipped to explore it. He charged $1 to go down with a candle, and if you didn’t re-emerge after 24 hours, he’d come and find you!
