Mid River Lane drops 284 vertical feet over 2,179 feet of skiing, with a steepest pitch of 20° about 2,140 feet below the top. That's steeper than 89% of the 3,109 green runs we've measured in North America, and the 85th steepest of 99 named runs at Sun Valley. It faces northeast.
Facing northeast at an average 8°, Mid River Lane gets about 60% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 85% of the runs we've measured, and the 48th shadiest named run at Sun Valley. Its top sits at 7,450 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.
