Mine Shaft drops 537 vertical feet over 1,379 feet of skiing, with a steepest pitch of 31° about 10 feet below the top. That's steeper than 30% of the 2,251 double black runs we've measured in North America, and the 89th steepest of 207 named runs at Breckenridge. It faces northwest.
Facing northwest at an average 23°, Mine Shaft gets about 57% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 87% of the runs we've measured, and the 20th shadiest named run at Breckenridge. Its top sits at 11,130 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.
