Blue Silver Mountain, ID
Collateral drops 793 vertical feet over 2,073 feet of skiing, with a steepest pitch of 28° about 1,330 feet below the top. That's steeper than 91% of the 5,615 blue runs we've measured in North America, and the 37th steepest of 69 named runs at Silver Mountain. It faces west.
Facing west at an average 23°, Collateral gets about 91% of the winter sun that flat ground at Silver Mountain does, December through March. That's sunnier than 61% of the runs we've measured, and the 15th sunniest named run at Silver Mountain. Its top sits at 5,660 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
