Castle drops 800 vertical feet over 3,819 feet of skiing, with a steepest pitch of 24° about 1,460 feet below the top. That's steeper than 18% of the 4,740 black diamond runs we've measured in North America, and the 17th steepest of 50 named runs at Sierra-At-Tahoe. It faces northwest.
Facing northwest at an average 12°, Castle gets about 75% of the winter sun that flat ground at Sierra-At-Tahoe does, December through March. That's shadier than 63% of the runs we've measured, and the 19th shadiest named run at Sierra-At-Tahoe. Its top sits at 8,310 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.
