A golfer uses a sand wedge to hit the ball from a green-side bunker. Also called a sand trap, a bunker is a depression near the putting green or fairway that is filled with sand. It is difficult to hit the ball out of the bunker and entering it is therefore considered punitive to a golfer who misses the target with the previous shot. After a player exits the bunker, golf etiquette requires that the area of the sand disturbed during play be raked.Photo credit: Eric Baetscher
