Green Clay

Green clay

Green clay, also known by brand names such as Har-Tru and Rubico, is made of crushed metabasalt rather than brick, making the surface slightly harder and faster than red clay. These courts are located primarily in the mid-Atlantic and southern United States. They are also found in Central and Eastern Canada. There is one WTA tournament played on green Har-Tru clay courts, the Charleston Open in Charleston, South Carolina. From 1975 until 1977, the US Open was played on Har-Tru clay courts.
