I remember watching this dam crack and flood on Superman 1, but I guess Superman saved the day because the dam looks just fine. During the tour I asked how long they expect this dam to last, given that the Mackinaw bridge was designed to last 1000 years. The response was 2000 years which surprised me. I guess two thousand years from now people will wonder if aliens built the dam. They also mentioned that there were a few missing people who were working on the dam and most likely fell in the cement. Probably not the best way to go.

In all seriousness the dam is a fascinating tour, a little warning to the ladies that you have to wear a hard hat on the tour inside so don’t do too much with your hair that day, you might end up with “helmet head”.
