North Berwick Law is a conical hill which rises incongruously from the surrounding landscape (indeed, this is the definition of the Lowland Scots word "law"). It overlooks the East Lothian town of North Berwick and stands at 613 ft (187 m) above sea level. Geologically, the law is a volcanic plug of hard phonolitic trachyte rock of Carboniferous age. It has survived the scraping glaciers of the ice age. It is a crag and tail with a prominent tail extending eastwards.
