"Smoo Cave" - watercolour - 18 x 26 cm
Smoo Cave, at Durness in the far North-west of Sutherland, is one the the main tourist attractions of the area. The cave was formed by the action of water dissolving the limestone rocks, leaving a series of chambers and underground waterfalls. Visitors can take a boat trip into the depths of the cavern.
Humans have been drawn to the cave from the earliest times: A midden in the entrance has been excavated and shows evidence of occupation from the Mesolithic Period through to the Iron Age. Other deposits indicate use of the cave in the Norse period. I'm sure it has continued to provide a shelter or hide-out at later times and has probably been used as a store more recently.
As well as the main cave, there are several smaller caves which may at one time have been part of one large cave system. There may still be other caves and passages, as yet undiscovered underground.
