Tombolo at Stockton Island, Ashland County, Apostle Islands, WI. Tombolos are islands connected to the mainland by current-deposited sands, which frequently form a series of parallel beach ridges. The bars or ridges may enclose a series of shallow interdunal swales, or larger lagoons within which thick organic soils and a dense growth of aquatic vegetation develop. The embayment created on the leeward side of the tombolo may receive sufficient protection from wave action that a fringe of emergent and submergent vegetation persists.
