Green Discovery, MT
Lum's Run drops 104 vertical feet over 1,004 feet of skiing, with a steepest pitch of 9° about 420 feet below the top. That's steeper than 16% of the 3,109 green runs we've measured in North America, and the 61st steepest of 62 named runs at Discovery. It faces southwest.
Facing southwest at an average 6°, Lum's Run gets about 109% of the winter sun that flat ground at Discovery does, December through March. That's sunnier than 79% of the runs we've measured, and the 18th sunniest named run at Discovery. Its top sits at 6,980 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.
