Black diamond Big Powderhorn, MI
Thunder drops 243 vertical feet over 1,007 feet of skiing, with a steepest pitch of 26° about 380 feet below the top. That's steeper than 31% of the 4,740 black diamond runs we've measured in North America, and the 6th steepest of 45 named runs at Big Powderhorn. It faces north.
Facing north at an average 14°, Thunder gets about 58% of the winter sun that flat ground at Big Powderhorn does, December through March. That's shadier than 86% of the runs we've measured, and the 5th shadiest named run at Big Powderhorn. Its top sits at 1,540 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.
