How well The Trap holds snow

Snow preservationExcellent

Facing north at an average 17°, The Trap gets about 59% of the winter sun that flat ground at Keystone does, December through March. That's shadier than 85% of the runs we've measured, and the 12th shadiest named run at Keystone. Its top sits at 11,890 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.
