Geologically Nave is interesting because it is split in two by a narrow cleft, some 6m wide. It was created by the erosion of a basalt dyke and it is almost completely impossible to cross due to its vertical sides.
There are interesting ruins on the south side of Nave. The ancient walls of an early thirteenth century chapel sprout a tall, 18th century brick built chimney! At first we thought we had found an illicit whisky distillery but the truth is less exotic. In 1785 the abandoned chapel was taken over to burn kelp. A broken section of a fine stone cross found in the floor of the chapel is believed to date from the 5th century. Clearly kelp burners had little thought of conservation. Until the development of the chemical industry in the 19th century, kelp burning in Scotland was the principal source of sodium carbonate for the manufacture of glass and soap.
