The Devil's Hole is a group of deep trenches in the North Sea about east of Dundee, Scotland.
The features, which were first charted by HMS Fitzroy, were officially recorded in the Royal Geographical Society's Geographical Journal in 1931. Soundings showed that the surrounding seabed is between but the trenches are as deep as . They run in a northâÂÂsouth direction and are on average between in width and long.
Historically, fishermen have known about the Devil's Hole for generations because they have lost trawl nets on the trenches' steep sides. It is for this reason that the area took its name.
The gradient of the trench sides in the Devil's Hole is up to 10ð in places. In a comparison, the continental shelf north west of Great Britain has an average gradient of 1ð.
