ENE entrance to a Cave/Subterranean passage/ Natural Arch. There is a 30 m long gloup slightly SW of the middle.

Stack O' Brough Stack O' Brough locally known as Scorrie's Island. It is possible to take a small boat through the natural arch in the stack where a blowhole acts as a skylight giving a Cathedral-like impression. [Fergus Mather]

The water level entrances are perhaps 2-3m wide and 15-20m high but the central shaft rises slightly of vertical with smooth sides to the top of the island.

Notes: The Stack of Brough is a tall isolated rock rising out of the sea containing an immense tunnel going from end to end. [Tony Oldham]

Scorrie's Island presumed to be a corruption of Sgurr (but is also Scots for Gull).
