Blue Spout Springs, OR
Alto drops 389 vertical feet over 2,192 feet of skiing, with a steepest pitch of 23° about 920 feet below the top. That's steeper than 66% of the 5,615 blue runs we've measured in North America, and the 10th steepest of 15 named runs at Spout Springs. It faces southwest.
Facing southwest at an average 10°, Alto gets about 113% of the winter sun that flat ground at Spout Springs does, December through March. That's sunnier than 82% of the runs we've measured, and the sunniest named run at Spout Springs. Its top sits at 5,440 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
