Double black Cypress Mountain, BC
Black Fly drops 484 vertical feet over 1,084 feet of skiing. It faces southeast.
Facing southeast at an average 27°, Black Fly gets about 135% of the winter sun that flat ground at Cypress Mountain does, December through March. That's sunnier than 94% of the runs we've measured, and the 23rd sunniest named run at Cypress Mountain. Its top sits at 3,360 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
