Double black Mount Bohemia, MI
Black Hole drops 288 vertical feet over 888 feet of skiing, with a steepest pitch of 30° about 230 feet below the top. That's steeper than 22% of the 2,251 double black runs we've measured in North America, and the 31st steepest of 125 named runs at Mount Bohemia. It faces south.
Facing south at an average 19°, Black Hole gets about 148% of the winter sun that flat ground at Mount Bohemia does, December through March. That's sunnier than 98% of the runs we've measured, and the 26th sunniest named run at Mount Bohemia. Its top sits at 1,040 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.
