This project, completed in December 2022, showcases the exciting new Warm Springs project at Sun Valley, Idaho. This project consists of constructing 2 brand new Doppelmayr detachable lifts. A quad, Lift A, will run on a new alignment connecting with Flying Squirrel, and a D-Line 6-pack, Challenger, will have the highest vertical rise of any chairlift in the US. Challenger will also feature a midway unloading area.
