Blue Copper, CO
Jackstraw Trees drops 314 vertical feet over 2,086 feet of skiing, with a steepest pitch of 20° about 890 feet below the top. That's steeper than 37% of the 5,615 blue runs we've measured in North America, and the 103rd steepest of 141 named runs at Copper. It faces east.
Facing east at an average 9°, Jackstraw Trees gets about 95% of the winter sun that flat ground at Copper does, December through March. That's sunnier than 66% of the runs we've measured, and the 30th sunniest named run at Copper. Its top sits at 10,730 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.
