A window of snowmaking temperatures appeared last week in the Northeast, allowing the snow guns to whiten the slopes at Vermont’s Killington and Maine’s Sunday River.

Snowmaking lit up on Killington and Skye Peaks just before 11:00 p.m. Monday, October 16, for testing prior to the season and the approaching Audi FIS Ski World Cup races, Nov. 24-26.  

While there is no confirmed window for opening day at this time, Killington often has the longest season in the East, stretching from October or November to May.

Killington has dedicated a snowmaking team to specifically build the race venue on Superstar where the women’s slalom and giant slalom races will take place. Killington’s snowmaking system has the ability to pump more than 720,000 gallons of water into 240 snow guns, covering 80 acres with 12 inches of fresh snow in a matter of hours.

In Maine, Sunday River made snow on their T2 trail on Locke Mountain, where the Maine resort typically vies for first to open in the East status.

Although Sunday River does not yet know when it will open for the winter season, the early-seasn snowmaking test brings it one step closer to its goal of opening as soon as possible. Eager early birds can now purchase the Kickstarter Pass at $159 for adults, $129 for teens and $99 for juniors for unlimited access to Sunday River from its opening day through December 24, 2017.

Proud to remain the ski resort with the longest season in Quebec, Sommet Saint-Sauveur also got the snow guns firing. Thanks to major investments this year, the Laurentians resort launched its snowmaking season earlier this year and on a wider terrain.

New Hampshire’s Cannon saw its coldest temps of the season (27 degrees on Oct. 17) and couldn't resist giving the system a test. They will fire up the guns with temps starting next week. Cannon is targeting a November 24 opening.
