Facing southeast at an average 9°, Mary's Mistake gets about 123% of the winter sun that flat ground at Whitecap Mountains does, December through March. That's sunnier than 88% of the runs we've measured, and the 10th sunniest named run at Whitecap Mountains. Its top sits at 1,600 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.
