What was the flood that killed a lot of people in a Colorado canyon? I just remember my dad telling me about that when we went by the place when younger. The thought of people trying to hang on to the side of cliffs for dear life just freaked me out.

That would have been the "Big Thompson" I remember driving up to see the aftermath when I was little. The damage was unreal. A dam broke. They didn't have a chance.
