Part Mardi Gras, part Halloween, the unofficial closing-day party at Alta is not for the faint of heart. Rain, snow or shine, partygoers gather on top of High Rustler in their finest (or weirdest) costumes for one final run. Unsanctioned and a bit out of control, High Boy ensures Alta goes out with a bang. This year, Alta's closing day is scheduled for Sunday, April 29.
