Blue Panorama, BC
Ostrander Alley drops 990 vertical feet over 3,031 feet of skiing. It faces northwest.
Facing northwest at an average 19°, Ostrander Alley gets about 60% of the winter sun that flat ground at Panorama does, December through March. That's shadier than 85% of the runs we've measured, and the 50th shadiest named run at Panorama. Its top sits at 5,450 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.

Measured by ZRankings from 30-meter elevation data from Natural Resources Canada, too coarse to measure steepness. Steepest pitch is the steepest stretch of about 50 vertical feet along the skiable line. Run lines come from OpenStreetMap and can sit a little off the skied path.
