Lower I-25 drops 260 vertical feet over 1,198 feet of skiing, with a steepest pitch of 19° about 810 feet below the top. That's steeper than 30% of the 5,615 blue runs we've measured in North America, and the 45th steepest of 88 named runs at Angel Fire. It faces north.
Facing north at an average 13°, Lower I-25 gets about 73% of the winter sun that flat ground at Angel Fire does, December through March. That's shadier than 66% of the runs we've measured, and the 34th shadiest named run at Angel Fire. Its top sits at 9,750 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.
