Ballhooter drops 320 vertical feet over 1,509 feet of skiing, with a steepest pitch of 30° about 640 feet below the top. That's steeper than 96% of the 5,615 blue runs we've measured in North America, and the 29th steepest of 140 named runs at Keystone. It faces northeast.
Facing northeast at an average 12°, Ballhooter gets about 84% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 52% of the runs we've measured, and the 62nd sunniest named run at Keystone. Its top sits at 10,180 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
