Time touring...
Not to live, but just visit:
The Lake Missoula Flood. That'd be cool to watch.
Eruptions of Yellowstone, or Valles Caldera (Jemez Mtns, New Mexico)
Scuba diving in a Cambrian Sea
A safari during the Eocene viewing weird mammals
A cruise on the Creatceous Intercontinental seaway
Okay, that was not the History you were refering to, But I couldn't help it.
I'd like to see Colorado before 1800.
Or during the gold rush. (Maybe that way I could get a hold of mine maps I need but can't find)
