Boundary Chutes drops 288 vertical feet over 737 feet of skiing, with a steepest pitch of 28° about 260 feet below the top. That's steeper than 17% of the 2,251 double black runs we've measured in North America, and the 111th steepest of 207 named runs at Breckenridge. It faces northeast.
Facing northeast at an average 23°, Boundary Chutes gets about 59% of the winter sun that flat ground at Breckenridge does, December through March. That's shadier than 85% of the runs we've measured, and the 26th shadiest named run at Breckenridge. Its top sits at 11,720 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.
