How well Big Thunder holds snow

Snow preservationBelow average

Facing west at an average 23°, Big Thunder gets about 94% of the winter sun that flat ground at Grand Targhee does, December through March. That's sunnier than 65% of the runs we've measured, and the 67th sunniest named run at Grand Targhee. Its top sits at 8,950 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.
