Blue Loon Mountain, NH
Boom Run drops 1,475 vertical feet over 8,164 feet of skiing, with a steepest pitch of 24° about 3,760 feet below the top. That's steeper than 68% of the 5,615 blue runs we've measured in North America, and the 21st steepest of 76 named runs at Loon Mountain. It faces north.
Facing north at an average 11°, Boom Run gets about 77% of the winter sun that flat ground at Loon Mountain does, December through March. That's shadier than 60% of the runs we've measured, and the 52nd shadiest named run at Loon Mountain. Its top sits at 2,460 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.
