Black diamond Discovery, MT
Sluice Box drops 928 vertical feet over 2,541 feet of skiing, with a steepest pitch of 28° about 1,670 feet below the top. That's steeper than 46% of the 4,740 black diamond runs we've measured in North America, and the 28th steepest of 62 named runs at Discovery. It faces southeast.
Facing southeast at an average 22°, Sluice Box gets about 152% of the winter sun that flat ground at Discovery does, December through March. That's sunnier than 98% of the runs we've measured, and the 2nd sunniest named run at Discovery. Its top sits at 7,960 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.
