The Engulfment of Yellowstone National Park was an event that occurred during the 2012 apocalypse. This event was concurrent with the Yellowstone Caldera Eruption (2012) while the Gordon Silberman and Curtis Family fled after retrieving the map to the Arks.
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 off 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 North America, engulfing many of its cities and rendering them uninhabitable.
- This event occurred in the same disaster that was occuring throughout the 2012 apocalypse, the Yellowstone Caldera Eruption of 2012.
