== Geography == The depression is drained by the rivers Hamme, Wümme and Wörpe. The Teufelsmoor extends over an area of about and is bordered in the west by the Wesermünde Geest and in the east by the Zeven Geest. The eponymous Teufelsmoor itself is an ombrotrophic raised bog that becomes a fen in the vicinity of the streams that drain it. It is one of the largest contiguous areas of bog in northwest Germany. Its largest extent is about 20 by 20 km. The oldest parts of the terrain in Grasberg have layers of peat eleven metres deep or more. In the centre of the moor is the Worpswede artists' colony, made famous by many landscape artists, which is near the sandy hill of the Weyerberg. Also well-known is the 'moor metropolis' of Gnarrenburg in the heart of the Teufelsmoor.
