Green Powderhorn, CO
Whistle Pup drops 40 vertical feet over 376 feet of skiing, with a steepest pitch of 10° about 360 feet below the top. That's steeper than 18% of the 3,109 green runs we've measured in North America, and the 46th steepest of 48 named runs at Powderhorn. It faces northwest.
Facing northwest at an average 6°, Whistle Pup gets about 86% of the winter sun that flat ground at Powderhorn does, December through March. That's sunnier than 55% of the runs we've measured, and the 2nd sunniest named run at Powderhorn. Its top sits at 8,430 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.
