Sister's Bowl Traverse drops 978 vertical feet over 3,979 feet of skiing, with a steepest pitch of 37° about 2,880 feet below the top. That's steeper than 53% of the 2,251 double black runs we've measured in North America, and the 25th steepest of 127 named runs at Snowbasin. It faces northeast.
Facing northeast at an average 15°, Sister's Bowl Traverse gets about 51% of the winter sun that flat ground at Snowbasin does, December through March. That's shadier than 92% of the runs we've measured, and the 7th shadiest named run at Snowbasin. Its top sits at 9,010 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.
