Black diamond Bear Valley, CA
Spyglass drops 334 vertical feet over 1,275 feet of skiing, with a steepest pitch of 24° about 630 feet below the top. That's steeper than 17% of the 4,740 black diamond runs we've measured in North America, and the 54th steepest of 74 named runs at Bear Valley. It faces north.
Facing north at an average 16°, Spyglass gets about 68% of the winter sun that flat ground at Bear Valley does, December through March. That's shadier than 74% of the runs we've measured, and the 38th shadiest named run at Bear Valley. Its top sits at 7,870 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.
