windlip
n.—Gloss: a snowdrift created by the wind in a high place. «“In Fairbanks there wasn’t any parks or jumps, so you just learned to hit whatever you had—natural hits, lips, windlips.”…Bell and Hebert link the tricks they first learned on hay-built jumps in Fairbanks with the natural terrain of big mountain riding, airing and spinning off windlips and cliffs and rarely stopping for even a second.…Bell’s most impressive move was a 720-degree spin off of a natural windlip.» —“Two snowboarders with Fairbanks ties try to conquer The North Face Masters” by Casey Grove Daily News-Miner (Fairbanks, Alaska) Apr. 13, 2008.
