Blue Snowmass, CO
Sunnyside drops 626 vertical feet over 2,538 feet of skiing, with a steepest pitch of 22° about 1,100 feet below the top. That's steeper than 54% of the 5,615 blue runs we've measured in North America, and the 96th steepest of 126 named runs at Snowmass. It faces east.
Facing east at an average 14°, Sunnyside gets about 110% of the winter sun that flat ground at Snowmass does, December through March. That's sunnier than 80% of the runs we've measured, and the 2nd sunniest named run at Snowmass. Its top sits at 10,610 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.
