Double black Park City, UT
Western Boundary drops 647 vertical feet over 1,432 feet of skiing, with a steepest pitch of 34° about 750 feet below the top. That's steeper than 38% of the 2,251 double black runs we've measured in North America, and the 75th steepest of 334 named runs at Park City. It faces south.
Facing south at an average 27°, Western Boundary gets about 155% of the winter sun that flat ground at Park City does, December through March. That's sunnier than 99% of the runs we've measured, and the sunniest named run at Park City. Its top sits at 8,990 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.
