Green Boyne Mountain, MI
William J drops 194 vertical feet over 2,423 feet of skiing, with a steepest pitch of 8° about 100 feet below the top. That's steeper than 10% of the 3,109 green runs we've measured in North America, and the 60th steepest of 61 named runs at Boyne Mountain. It faces northwest.
Facing northwest at an average 5°, William J gets about 93% of the winter sun that flat ground at Boyne Mountain does, December through March. That's sunnier than 64% of the runs we've measured, and the 20th sunniest named run at Boyne Mountain. Its top sits at 1,030 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.
