The long field goals by Elam, Janikowski, and Prater were all made in Denver, where the ball has the ability to travel slightly farther in thinner air. Elam kicked his 63-yard field goal at Mile High Stadium, while the 63-yarder by Janikowski and the 64-yarder by Prater were at Sports Authority Field at Mile High. In track and field, the IAAF denotes any records set 1,000 metres (about 3,937 feet) or more above sea level as altitude-assisted records, and the Dempsey (Tulane Stadium) and Akers (Lambeau Field) records were set below the 1,000m threshold.
