Hal's Hollow (Upper) drops 339 vertical feet over 1,350 feet of skiing, with a steepest pitch of 25° about 1,110 feet below the top. That's steeper than 75% of the 5,615 blue runs we've measured in North America, and the 87th steepest of 126 named runs at Snowmass. It faces northeast.
Facing northeast at an average 15°, Hal's Hollow (Upper) gets about 72% of the winter sun that flat ground at Snowmass does, December through March. That's shadier than 68% of the runs we've measured, and the 71st shadiest named run at Snowmass. Its top sits at 9,660 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
