Black diamond Alpine Meadows, CA
Lower 40 Gully drops 175 vertical feet over 1,141 feet of skiing, with a steepest pitch of 21° about 130 feet below the top. That's steeper than 9% of the 4,740 black diamond runs we've measured in North America, and the 115th steepest of 132 named runs at Alpine Meadows. It faces west.
Facing west at an average 9°, Lower 40 Gully gets about 107% of the winter sun that flat ground at Alpine Meadows does, December through March. That's sunnier than 77% of the runs we've measured, and the 34th sunniest named run at Alpine Meadows. Its top sits at 7,030 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
