Green Park City, UT
Upper Mainline drops 334 vertical feet over 3,513 feet of skiing, with a steepest pitch of 13° about 1,230 feet below the top. That's steeper than 43% of the 3,109 green runs we've measured in North America, and the 317th steepest of 334 named runs at Park City. It faces southeast.
Facing southeast at an average 6°, Upper Mainline gets about 104% of the winter sun that flat ground at Park City does, December through March. That's sunnier than 75% of the runs we've measured, and the 62nd sunniest named run at Park City. Its top sits at 8,630 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.
