Oh Em Gee! I'm not surprised, but still amazed how bad decisions like this can seem smart. In my teens, I worked in Yellowstone and I can tell you that every ranger has a collection of stories about bad decisions like this.

We were told about the thin crusts around thermal features, and in a couple of instances some breakthroughs (from bison trying to say warm over winter) were pointed out to us. My teenage brain didn't think they looked like much, but I still kept my distance.
