Black diamond Silver Mountain, ID
Eureka drops 427 vertical feet over 1,279 feet of skiing, with a steepest pitch of 35° about 90 feet below the top. That's steeper than 83% of the 4,740 black diamond runs we've measured in North America, and the 13th steepest of 69 named runs at Silver Mountain. It faces northeast.
Facing northeast at an average 20°, Eureka gets about 59% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 86% of the runs we've measured, and the 23rd shadiest named run at Silver Mountain. Its top sits at 5,940 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.
