Category:Baas, Skerries, and Sea Stacks
Baa is the Shetland name for a submerged rock.
Many of the most recognised baas is the area have become so because of the hazard they represent to shipping, as well as being important Meids (fishing marks).
Some of the baas are visible above water at very low tide, whilst others are only evidenced by the breaking surf.
Some of the deeper ones only cause breaking surf in extreme weather conditions. These ones are less of a hazard to vessels, but are often good fishing locations.
Skerry is the Shetland word for a small rock, or mini islet, which is generally always visible above the water. The obvious exception to this, is of course the Out Skerries which have two inhabited islands.
Of the many skerries around the coast of Shetland, the Ve Skerries are the most notable because of their history as a hazard to shipping.
A Sea Stack is a pillar-like eroded remnant of a coastal cliff. Stacks may develop from arches when the keystone of the former arch collapses but can develop from direct erosion of a headland or a cliff as well.
There are many sea stacks around Shetland, perhaps the most famous, and most photographed, is the series of stacks in St Magnus Bay called The Drongs.
