Ski/Border Cross Course drops 110 vertical feet over 822 feet of skiing, with a steepest pitch of 11° about 730 feet below the top. That's steeper than 1% of the 4,740 black diamond runs we've measured in North America, and the 51st steepest of 61 named runs at Boyne Mountain. It faces north.
Facing north at an average 8°, Ski/Border Cross Course gets about 76% of the winter sun that flat ground at Boyne Mountain does, December through March. That's shadier than 62% of the runs we've measured, and the 11th shadiest named run at Boyne Mountain. Its top sits at 1,010 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.
