Hype (geomorphology)
Rummel is a name commonly used in Hohen Fläming for the periglacial dry valleys that are common here and that have been deeply deepened due to the human-made soil erosion . Typical for the Hohen Fläming is its highly branched system of narrow, 6 to 12 meters deep valley systems, called Rummeln. The name is probably derived from "Ramel" from the Magdeburg area or the Mecklenburg word "Rämel". Both mean groove or furrow. The grammatically correct singular is "die Rummel".
They owe their creation to erosion by water. During the Vistula ice age, the Fläming was free of ice, but the ground was constantly frozen ( permafrost ). The meltwater from the snow cover, which thawed in summer, could not seep into the ground. They flowed off superficially and formed ever deeper valleys. At the end of the Ice Age, these mostly had relatively flat, trough-like slopes. In the age of medieval clearing, when the protective forest cover was missing, precipitation could significantly deepen the valley floor and thus create the hype. In the event of heavy rainfall or when the snow melts over frozen ground, some hustle and bustle can still have water today. However, they are dry for most of the year. The narrow, steep and up to 3 km long valleys, in which hardly any arable farming could be practiced, are very significant as a refuge for animal and plant species of the heather and grassland .
