Black diamond Sugarloaf, ME
Sheer Boom drops 629 vertical feet over 1,742 feet of skiing, with a steepest pitch of 31° about 280 feet below the top. That's steeper than 66% of the 4,740 black diamond runs we've measured in North America, and the 22nd steepest of 148 named runs at Sugarloaf. It faces north.
Facing north at an average 21°, Sheer Boom gets about 39% of the winter sun that flat ground at Sugarloaf does, December through March. That's shadier than 98% of the runs we've measured, and the 5th shadiest named run at Sugarloaf. Its top sits at 3,080 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.
