How well Deep South holds snow

Snow preservationPoor

Facing southeast at an average 9°, Deep South gets about 112% of the winter sun that flat ground at Big Sky does, December through March. That's sunnier than 81% of the runs we've measured, and the 82nd sunniest named run at Big Sky. Its top sits at 8,760 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.
