Green Sun Valley, ID
Gun Tower Lane drops 293 vertical feet over 4,340 feet of skiing, with a steepest pitch of 6° about 2,400 feet below the top. That's steeper than 6% of the 3,109 green runs we've measured in North America, and the 99th steepest of 99 named runs at Sun Valley. It faces southeast.
Facing southeast at an average 4°, Gun Tower Lane gets about 122% of the winter sun that flat ground at Sun Valley does, December through March. That's sunnier than 88% of the runs we've measured, and the 6th sunniest named run at Sun Valley. Its top sits at 7,680 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.
