corduroy
n.— «For the next seven hours, John “Bish” Neuhauser and eight swing-shift co-workers chugged up and down assigned areas of this expansive Park City-area resort in snowcats. They pushed snow around and combed it into a level surface of parallel grooves, fine “corduroy” in industry parlance.» —“Good grooming a must for elite resorts” by Mike Gorrell Salt Lake Tribune (Utah) Jan. 31, 2009.
