Caption: The Gaylet Pot, 4.0 km. north-east of Arbroath, Angus. A 'gloup' or blowhole, the collapsed roof of a cave eroded along joints in the Lower Old Red Sandstone (Lower Devonian) opening at the foot of a sea cliff, a distance of over 137 m.
Description: The Gaylet Pot, 4.0 km. north-east of Arbroath, Angus. A 'gloup' or blowhole, the collapsed roof of a cave eroded along joints in the Lower Old Red Sandstone (Lower Devonian) opening at the foot of a sea cliff, a distance of over 137 m. This vertical hole is formed from the collapse of the inner end of a sea cave. Incoming waves and rising tide forcibly compressing the air along a line of weakness, in this case a joint. This initially forms a cave, repeated compressing at the end of the cave causes concentrated erosion along and up the joint until it breaks though to the surface as in the photograph. This can be a considerable distance inland.
