Caption: Wife Geo, 2.25 m. south of Duncansby Head. Caithness.
Description: The removal of the enormous amount of debris fallen down from the roof and sides through the narrow entrances, is due to the flat nature of the material into which the flagstones break up, giving purchase to the undertow. Caves are excavated often for great lengths, along the joints which are belts of weakness. With the collapse of the roof and removal of debris, long narrow inlets are formed. In Scotland this type of inlet is called geo (from the Norse gya, a creek). This 'geo' the largest in Caithness, has been excavated in Thurso Flagstones (Old Red Sandstone) by undermining between the main joints. One of the two tunnels remains, the other now forming the main entrance.
