Black diamond Winter Park, CO
Thunderbird drops 1,047 vertical feet over 3,445 feet of skiing, with a steepest pitch of 24° about 240 feet below the top. That's steeper than 21% of the 4,740 black diamond runs we've measured in North America, and the 87th steepest of 164 named runs at Winter Park. It faces northwest.
Facing northwest at an average 18°, Thunderbird gets about 68% of the winter sun that flat ground at Winter Park does, December through March. That's shadier than 74% of the runs we've measured, and the 34th shadiest named run at Winter Park. Its top sits at 11,500 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.
