Black diamond A-Basin, CO
Torreys drops 433 vertical feet over 1,383 feet of skiing, with a steepest pitch of 32° about 960 feet below the top. That's steeper than 70% of the 4,740 black diamond runs we've measured in North America, and the 96th steepest of 161 named runs at A-Basin. It faces northwest.
Facing northwest at an average 19°, Torreys gets about 82% of the winter sun that flat ground at A-Basin does, December through March. That's shadier than 51% of the runs we've measured, and the 108th shadiest named run at A-Basin. Its top sits at 11,800 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
