snowdrift. The best known use of this word comes from the evocative line of Hugh McDiarmid in ‘The Eemis Stane’ from his Sangschaw collection (1925): An’ my eerie memories fa’ Like a yowdendrift. The lightness of snow is apparent in Douglas Young’s Braird o’ Thristles (1947): Skinklan pouther frae a licht yowden-drift o’ snaw.
