The Engulfment of Yellowstone National Park was an event that occurred during the 2012 apocalypse.
Around Midday of December 21st 2012, the Yellowstone Caldera erupted, causing volcanic bombs, lava and a pyroclastic flow to spread around the park, destroying all of its landmarks, forests, the military campsite and killing the park's wildlife.
The Curtis Family (Jackson, Kate, Noah and Lilly Curtis) and Gordon Silberman are the only people who have witnessed the eruption and have escaped on board a Cessna plane, with a map from Charlie Frost, a radio host and conspiracy theorist, that shows the location of the Arks, before the ash cloud nearly engulfed them.
The giant ash cloud continued to spread around the United States, Mexico and Canada, engulfing many of its cities and rendering them uninhabitable. The ash cloud hit Las Vegas, St. Louis, Chicago and Washington D.C.
- This event occurred in the same disaster that was occuring throughout the 2012 apocalypse, the Yellowstone Caldera Eruption of 2012.
