Blue Boyne Mountain, MI
Aurora drops 390 vertical feet over 1,604 feet of skiing, with a steepest pitch of 23° about 560 feet below the top. That's steeper than 66% of the 5,615 blue runs we've measured in North America, and the 9th steepest of 61 named runs at Boyne Mountain. It faces northeast.
Facing northeast at an average 14°, Aurora gets about 73% of the winter sun that flat ground at Boyne Mountain does, December through March. That's shadier than 67% of the runs we've measured, and the 7th shadiest named run at Boyne Mountain. Its top sits at 1,150 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
