’Glacial erratic at Zoutkamp.’

	A glacial erratic (Dutch: zwerfsteen) lines the southern bank of the Reitdiep river at Zoutkamp. These large boulders where deposited by glaciers in the northern Netherlands during the Saale ice-age (around 200.000 years ago). On the opposite bank of the river the brightly coloured wooden houses of Zoutkamp can be seen. The Reitdiep formed the only navigable waterway between the sea and the town of Groningen till well into 19th century. Photo Mick Palarczyk.
