What is another word for sand greens?
Pronunciation: [sˈand ɡɹˈiːnz] (IPA) 
Sand greens are a type of putting surface commonly found on older golf courses. Synonyms for sand greens include oil greens, dirt greens, and sand traps. Oil greens were used in the earliest days of golf and were made by pouring oil onto existing surfaces. Dirt greens were created by cutting holes in the ground and filling them with sand or soil. Sand traps, or bunkers, are similar to sand greens in that they are filled with sand, but they are usually hazards that players try to avoid. Although sand greens are not as common as they once were, they remain a part of golf history and are cherished by some players for their challenge and uniqueness.
