St Ninians Tombolo, Shetland
Definition: a spit that connects the mainland with an island
Although tombolos are by no means rare in archipelagos, they are numerically few relative to other classic forms of marine deposition. In the Northern Isles, tombolos are known locally as ayres (Old Norse Eyrr - gravel beach). The majority are formed of materials coarser than sand, including gravel, cobbles or, occasionally, boulders. The ayre at St Ninian's Isle is the largest active sand tombolo in Britain.
