Black diamond A-Basin, CO
Log Roll drops 346 vertical feet over 1,301 feet of skiing, with a steepest pitch of 38° about 620 feet below the top. That's steeper than 92% of the 4,740 black diamond runs we've measured in North America, and the 51st steepest of 161 named runs at A-Basin. It faces south.
Facing south at an average 16°, Log Roll gets about 131% of the winter sun that flat ground at A-Basin does, December through March. That's sunnier than 93% of the runs we've measured, and the 15th sunniest named run at A-Basin. Its top sits at 11,860 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.
