Years ago I visited Mammoth Cave, KY. There I learned about cave explorer Floyd Collins. He was trapped in a cave in 1925 and the incident attracted wide attention. I started reading about Collins and this is still one of the most terrifying reads for me. I cannot imagine being trapped so tightly, underground with no light and for so long.

There was a musical made of this in the 90s. I saw it at the Goodman Theatre in Chicago. Didn't make me as nervous as reading the account of the spiral passageway barely able to fit a human.

This is one of the most harrowing stories that I have ever read.
