just in case anyone else was curious: Acer Saccharum
"Sugar maple wood is the hardest and strongest maple wood. It polishes well and is widely used for furniture, cabinets, and violins and other musical instruments. It is also used for making bowling alleys. Some sugar maple wood has an unusual grain pattern that makes it particularly beautiful and valuable. This wood, called curly maple or bird's eye maple, is used in fine furniture and stringed musical instruments."
unfortunately, those of us in Colorado don't have all that many sugar maples around... mostly silver maple and norway maple.
