Green Snow Valley, CA
Thunder Mountain drops 118 vertical feet over 1,345 feet of skiing, with a steepest pitch of 13° about 10 feet below the top. That's steeper than 39% of the 3,109 green runs we've measured in North America, and the 25th steepest of 28 named runs at Snow Valley. It faces north.
Facing north at an average 5°, Thunder Mountain gets about 91% of the winter sun that flat ground at Snow Valley does, December through March. That's sunnier than 61% of the runs we've measured, and the 6th sunniest named run at Snow Valley. Its top sits at 6,840 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
