"Get out of Yellowstone! It's gonna get ugly!"
- Charlie Frost
Yellowstone National Park was a national park located primarily in the U.S. state of Wyoming, although it also extended into Idaho and Montana. The park was destroyed when Yellowstone's caldera erupted in 2012, leading to the entire area to become a super-volcano big enough to create an ash cloud that can swallow the entire United States.
- In the film, it at first (when Jackson drives) appears to be close to Los Angeles, but in reality it is much (much) further away, that Jackson would need a big plane to fly there and back in a short time.
- Additionally, in Los Angeles, Jackson could also catch Charlie's radio signals/broadcast, while Charlie was in Yellowstone, in reality, it would be too far to pickup.
