Natural abstract pattern in the sandy shore of River Dinkel

River Dinkel and Dinkel Valley, nature reserve Lutterzand in De Lutte, the Netherlands - Province Twente. Erosion, wind and rain have created a whimsical pattern of natural sand sculptures in the sandy shore of the river. The River Dinkel streams between the moraine of Ootmarsum and the moraine of Oldenzaal. It's an active, freely meandering river. Sediments that in the past 130.000 years were deposited by wind and rivers are broached again and deported by the Dinkel. In the Lutterzand Nature reserve, the Dinkel has cut in deeply in its own sediments, revealing several historic earth layers in its shores.
