Blue Terry Peak, SD
Surprise drops 384 vertical feet over 1,688 feet of skiing, with a steepest pitch of 19° about 520 feet below the top. That's steeper than 31% of the 5,615 blue runs we've measured in North America, and the 21st steepest of 26 named runs at Terry Peak. It faces north.
Facing north at an average 13°, Surprise gets about 61% of the winter sun that flat ground at Terry Peak does, December through March. That's shadier than 83% of the runs we've measured, and the 6th shadiest named run at Terry Peak. Its top sits at 6,710 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.
