Black diamond Eldora, CO
Corrona drops 235 vertical feet over 1,025 feet of skiing, with a steepest pitch of 26° about 140 feet below the top. That's steeper than 29% of the 4,740 black diamond runs we've measured in North America, and the 17th steepest of 58 named runs at Eldora. It faces northeast.
Facing northeast at an average 13°, Corrona gets about 68% of the winter sun that flat ground at Eldora does, December through March. That's shadier than 75% of the runs we've measured, and the 4th shadiest named run at Eldora. Its top sits at 9,520 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.
