One of the most pristine natural bottom reefs along the Gulf Coast. This reef system gets its name from the perfectly round holds that populate the reef. Theorized as being formed from trees (timber) that once grew through the limestone when sea levels were much lower. This reef is loaded with photo opportunities but be prepared with your dive computer because the depth runs from 100 to 110 feet. Large ledges rise 6-10 feet from the bottom and hold every type of tropical fish known in the Gulf.
