Christina's Trail, Heidi's Playground drops 3 vertical feet over 13 feet of skiing, with a steepest pitch of 12° about 0 feet below the top. That's steeper than 31% of the 3,109 green runs we've measured in North America, and the 31st steepest of 39 named runs at Afton Alps. It faces northeast.
Facing northeast at an average 12°, Christina's Trail, Heidi's Playground gets about 71% of the winter sun that flat ground at Afton Alps does, December through March. That's shadier than 69% of the runs we've measured, and the 7th shadiest named run at Afton Alps. Its top sits at 830 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 1-meter USGS lidar. 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.
