The western third of the state contains numerous mountain ranges; other 'island' ranges are found in the central third of the state, for a total of 77 named ranges of the Rocky Mountains. This geographical fact is reflected in the state's name, derived from the Spanish word montaña (mountain). The state ranks fourth in area, but 44th in population, and therefore has the third lowest population density in the United States.
Montana was directly impacted by the eruption of the Yellowstone Supervolcano, with several towns next to Yellowstone National Park wiped off the map altogether. The President declared a state of emergency in Montana and the governor called out the National Guard. The western part of the state did manage to sustain itself for a time, if barely.
In the initial aftermath of the eruption, Kelly Birnbaum was able to find shelter in Missoula, Montana, which was just outside of the blast-zone.
