The City of Lincoln is the capital and the second-most populous city of the US state of Nebraska. (Omaha is the first.) It is named after Abraham Lincoln, the 16th President of the United States. Lincoln is also the county seat of Lancaster County and the home of the University of Nebraska. Lincoln's 2010 Census population was 258,379.
Bryce Miller was on an airliner flying from O'Hare to LAX when the Yellowstone Supervolcano erupted causing the flight to divert to Lincoln, Nebraska. However, the shock-wave and ash from the eruption hit the aircraft before it could land causing the engines to shut down. The pilot succeeded in "pulling a Sully", that is gliding the stricken plane into a water landing onto Branch Oak Lake. All passengers managed to get off the plane and those who were not hospitalized, the Red Cross put them up temporarily in a Motel 6 in Lincoln.
While stuck in Lincoln, Miller gravitated to the university campus, both for its own sake and because he had a slight acquaintanceship with some of the facility and their grad students from various conferences. Marcus Wilson, one such student, took him to a local museum which had artifacts from the Ashfall State Historical Park. These were the fossil remains of various animals from a supervolcano eruption 12,000,000 years ago.
