Cloppenburg Geest, Geographic formation in Lower Saxony, Germany.

Cloppenburg Geest is a geest region near Cloppenburg in North Germany, stretching from Herzlake in the west to Barnstorf in the east and from Wildeshausen in the north to Vechta in the south. Its surface is cut by numerous parallel, flat meltwater channels that create a landscape of parallel ridges. Meltwater sands of advancing glaciers lie beneath a boulder clay cover of the Saale glaciation, Drenthe stage.

The area formed during the Saale glaciation when boulder clay was deposited over outwash sands, creating the foundation of the current geological structure. These layers continue to shape the terrain and drainage patterns we see today.

The geest lies between Herzlake and Barnstorf, Wildeshausen and Vechta, covering southern Cloppenburg and Oldenburg districts and northern Vechta district. Its parallel flat channels and ridges, described by Woldstedt in 1955, shaped the river network; the Herrenholz woods, the Baumweg nature reserve and the Bäken der Endeler and Holzhauser Heide are protected FFH areas.

The Cloppenburg Geest stretches from Herzlake in the west to Barnstorf in the east and from Wildeshausen in the north to Vechta in the south, covering southern Cloppenburg and Oldenburg districts and northern Vechta district, and reaching into Diepholz and Emsland. The Herrenholz woodland, the Baumweg nature reserve and the Bäken der Endeler und Holzhauser Heide reserve are protected FFH areas.

The area is crossed by meltwater valleys that played a key role in developing the river network still seen today. These valleys still show clear marks from ice-age water flow and shape the landscape pattern today.
