Black diamond Alta, UT
Gravy Boat drops 174 vertical feet over 541 feet of skiing, with a steepest pitch of 31° about 70 feet below the top. That's steeper than 62% of the 4,740 black diamond runs we've measured in North America, and the 72nd steepest of 117 named runs at Alta. It faces northwest.
Facing northwest at an average 19°, Gravy Boat gets about 71% of the winter sun that flat ground at Alta does, December through March. That's shadier than 69% of the runs we've measured, and the 36th shadiest named run at Alta. Its top sits at 10,500 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.
