Black diamond Bogus Basin, ID
Eureka drops 461 vertical feet over 1,191 feet of skiing, with a steepest pitch of 30° about 30 feet below the top. That's steeper than 60% of the 4,740 black diamond runs we've measured in North America, and the 18th steepest of 98 named runs at Bogus Basin. It faces north.
Facing north at an average 23°, Eureka gets about 38% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 98% of the runs we've measured, and the shadiest named run at Bogus Basin. Its top sits at 6,280 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
