SnowBrains | | Industry NewsIndustry News

Sun Valley, Idaho is thrilled to announce that despite the recent pandemic the addition of 380 skiable acres to Bald Mountain for this upcoming winter will still be going ahead. This project started last summer with the additional snowmaking and this summer the bulk of the project will be completed.

When the project is complete, in the Fall of 2020, it will include replacing the resort’s oldest chairlift, Cold Springs (#4), with a new high-speed detachable quad lift, providing a seamless transition to The Roundhouse restaurant, the Roundhouse Express Gondola, and Christmas (#3) chairlift. For those who prefer groomers and gradual pitches, the Lower Broadway run is being extended, lined with 25 highly-efficient snowmaking guns.

Construction began in 2018 with the re-routing and redevelopment of the Cold Springs mountain bike trail, grading of the Lower Broadway run, tree removal, and excavation work. The project continued in Summer 2019 with 25 highly-efficient snowmaking guns placed along the extended Lower Broadway run, glading, and terrain enhancement. The installation of utilities and the new chairlift will happen in Summer 2020, with the increased terrain, high-speed detachable quad lift, and additional snowmaking ready for Winter 2020-21.

Replacement of the Cold Springs (#4) Chairlift

The main purpose of the project is the replacement of the Cold Springs (#4) chairlift, the oldest lift still operating at the resort.

  • The new chairlift will be a high-speed detachable quad that will have a vertical rise of 1582’ and be 5535’ long.
  • It will be a seamless ride from the new lower lift terminal to The Roundhouse.
  • Lower Broadway (similar width and gradient as existing ski run) will be extended 4,200.’

Increased Skiable Terrain

  • Skiable acreage within the Sun Valley Resort boundary will increase from 2,054 acres to 2,434 acres (380 acres) when the project is done.
  • Access from the top of Seattle Ridge, where skiers and riders may descend into “Turkey Bowl,” then proceed north for access to extensive tree skiing.

Increased Snowmaking

  • Increased snowmaking with 25 highly-efficient snowmaking guns extending down Lower Broadway to the base of the new lift lower terminal.
  • Rerouted and Improved Cold Springs Mountain Bike Trail

The Cold Springs mountain bike trail was rerouted and improved with more singletrack and shaded riding.
