Columbia was the first breed developed in the U.S. beginning in 1912 from Lincoln x Rambouillet crosses. Columbias are a hardy and gregarious breed and make good mothers. They are one of the larger-sized breeds in the U.S., have white faces with wool extending down the legs and are increasingly used as terminal sires to produce fast-growing, lean market lambs. They yield heavy, medium-wool fleeces with good staple length.
