Brackvenn Moor Lakes

What is often called a lake in the Fens is often e.g. Palsas.
The palsen or pingos in the High Fens were formed around 10,000 to 11,000 years ago at the end of the last ice age. When the ground froze deep down during the cold winters of the Ice Age, the wet ground expanded and frost mounds developed. Over the years these mounds grew and the soil material that was on top slid down the sides of the mounds and over time formed a ring-shaped wall around the mound of frost. With the end of the ice age, the ice melted, the frost mound sagged and the wall was preserved. The water in the middle is called bog scour or bog eye.

Anyone who sees the beauty of the raised and low moors will never be able to let it go.
The colors of the landscape, indeed the entire appearance of the High Fens, change dramatically every season. Even in winter - a breathtakingly beautiful landscape.

The peat that can be found everywhere in the bog and fen areas is the result of a process of incomplete decomposition. Usually, dead plants are gradually decomposed by small animals (such as earthworms), bacteria and fungi. This process applies to well-drained soils. On impervious acidic soils that do not contain many bacteria and in humid climates, plants such as peat moss are only partially decomposed. Their superimposition forms the peat layer. This peat layer can be up to 7 m in certain places here in the Brackvenn. 1 mm layer of peat takes 1 year to form. With a peat layer of 7 m, for example, we are talking about a period of 7,000 years.
