As the birthplace of Aspen skiing, Aspen Mountain has many historic traditions for closing day. For example, locals gather atop Ridge of Bell at 1 p.m. for the infamous "Bump Off," a kamikaze race down the mogul field under the gondola. Spectators gather on Gent's Ridge to watch as skiers either make it or explode, with both results giving the crowds what they want!

Aspen Snowmass hosts closing-day celebrations at the Sundeck. A recent theme was 80's Prom and included a live DJ and a costume contest.

At the base of Aspen Mountain, Ajax Tavern and Chica will turn up the music at dueling apres-ski parties, and the sunny patios will stay rocking until well after the lifts have stopped spinning.
