Blue Waterville Valley, NH
Rock Island drops 482 vertical feet over 2,662 feet of skiing, with a steepest pitch of 20° about 2,600 feet below the top. That's steeper than 38% of the 5,615 blue runs we've measured in North America, and the 36th steepest of 65 named runs at Waterville Valley. It faces east.
Facing east at an average 11°, Rock Island gets about 96% of the winter sun that flat ground at Waterville Valley does, December through March. That's sunnier than 68% of the runs we've measured, and the 16th sunniest named run at Waterville Valley. Its top sits at 2,450 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
