Black diamond Whiteface Mountain, NY
Upper Thruway drops 866 vertical feet over 2,271 feet of skiing, with a steepest pitch of 29° about 230 feet below the top. That's steeper than 53% of the 4,740 black diamond runs we've measured in North America, and the 20th steepest of 90 named runs at Whiteface Mountain. It faces east.
Facing east at an average 23°, Upper Thruway gets about 91% of the winter sun that flat ground at Whiteface Mountain does, December through March. That's sunnier than 61% of the runs we've measured, and the 73rd sunniest named run at Whiteface Mountain. Its top sits at 3,030 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.
