Jeff's Line drops 782 vertical feet over 2,239 feet of skiing, with a steepest pitch of 33° about 380 feet below the top. That's steeper than 74% of the 4,740 black diamond runs we've measured in North America, and the 28th steepest of 58 named runs at Kirkwood. It faces northeast.
Facing northeast at an average 21°, Jeff's Line gets about 77% of the winter sun that flat ground at Kirkwood does, December through March. That's shadier than 60% of the runs we've measured, and the 29th shadiest named run at Kirkwood. Its top sits at 8,760 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.
