The Sun Valley Resort’s Dollar Mountain  Super Pipe will open this Wednesday, December 21.

This will mark the historical debut of the world’s first chairlifts on Dollar and Proctor Mountain 75 years ago to the day.

This new Super Pipe is only the fifth  to open in the U.S. so far this season and the first in the Northwest. The pipe will measure 18-feet high, 437 feet long and will be located in Dollar’s Old Bowl.

The structure was designed and built Sun Valley’s Terrain Park Team, assisted by Snow Park Technologies.

The Super Pipe will open to skiers and riders at 9 am.
