Black diamond Silver Mountain, ID
Happy Jack drops 454 vertical feet over 1,010 feet of skiing, with a steepest pitch of 33° about 490 feet below the top. That's steeper than 78% of the 4,740 black diamond runs we've measured in North America, and the 18th steepest of 69 named runs at Silver Mountain. It faces south.
Facing south at an average 27°, Happy Jack gets about 164% of the winter sun that flat ground at Silver Mountain does, December through March. That's sunnier than 99% of the runs we've measured, and the sunniest named run at Silver Mountain. Its top sits at 5,660 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.
