Black diamond Afton Alps, MN
Sally's Valley drops 177 vertical feet over 627 feet of skiing, with a steepest pitch of 22° about 380 feet below the top. That's steeper than 13% of the 4,740 black diamond runs we've measured in North America, and the 5th steepest of 39 named runs at Afton Alps. It faces southeast.
Facing southeast at an average 17°, Sally's Valley gets about 121% of the winter sun that flat ground at Afton Alps does, December through March. That's sunnier than 88% of the runs we've measured, and the 2nd sunniest named run at Afton Alps. Its top sits at 890 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.
