The region between the Elbe and Weser rivers (the triangle of Bremen, Hamburg, and Cuxhaven) forms the Elbe–Weser triangle (German: Elbe-Weser-Dreieck; Northern Low Saxon: Elv-Werser-Dreeeck), also rendered Elbe-Weser Triangle,[1][2][3] in northern Germany. It is also colloquially referred to as the Nasses Dreieck or "wet triangle".
The Elbe–Weser triangle is a geographicalregion and, historically and politically, corresponds roughly to the former territory of Bremen-Verden and formed the major part of the former Stade Region. Today the Elbe–Weser triangle belongs to Lower Saxony outside the borders of the Hanseatic cities. The Stade Regional Association (Landschaftsverband Stade) operates within the Elbe–Weser triangle as a regional cultural organisation.
The terrain is largely flat and comprises mudflats, marsh, bog and geest, mainly the Stade Geest. Other areas are characterised by partially dried out bog, such as the Teufelsmoor or the Altes Land and raised bogs, like the Ahlenmoor, Langes Moor, Hymenmoor and Königsmoor, with peat layers of two to six metres. Typical of the scenery are broad ridges of geest, often covered with pine or mixed woods, heathland and natural rivers such as the Oste, Geeste, Lower Elbe, Lune, Hamme or the Wümme. In the northern part of the area the only ridge is the Wingst, up to 74 metres (243 ft) high.
The basis of the terrain is largely formed from the moraines and meltwater deposits of the Saalian glaciation, the penultimate glaciation period of the pleistocene era. These have created the sand ridges of the geest with their typical glacial erratic boulders of granite and gneiss. The end moraines of the last ice age (Weichselian ice age) did not reach this area. The contours of the land are much softer and flatter than, e.g. in the Holstein Switzerland.
There are sea ports in Bremerhaven, Bremen, Cuxhaven and Bützfleth. Inland shipping is able to use the rivers Aller, Oste and several canals; the Weser and Elbe can also be used by sea-going vessels.
Regional airports and airfields are located at Bremerhaven-Luneort, Nordholz, Rotenburg-Luhne and Hellwege.
In the Triangle, with its geest, moorland and bogs, there are large numbers of monuments and reminders of prehistoric and early historic and more recent historic times. These include:
