Facing northeast at an average 25°, The Triangle (Lower) gets about 43% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 96% of the runs we've measured, and the 7th shadiest named run at Bogus Basin. Its top sits at 6,930 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.
