The fact that the Feldberg lake landscape has been shaped by the ice age is noticed quite quickly. Just before Carwitz, near the border between Mecklenburg and Brandenburg, however, you see something very special: a stone mammoth. Here, committed citizens have prevented an open-cast gravel mine, in whose place an erratic boulder garden has now been created.
Southwest of Carwitz, an open-pit gravel mine was once to be built due to the quantities of sand brought here by the last ice age. The outwash areas at the end of the glacial series are predestined for this, and it would not have been the first in the area. However, citizens' initiatives from both federal states successfully resisted the open pit mine and erected a boulder garden at the designated site. The largest specimen is an erratic boulder weighing 20 tons, which from now on will watch over the weal and woe of the local landscape as a "guardian". Other boulder stones trace the outline of a mammoth. The origin of the boulders is explained on various information boards. The erratic boulder garden is one project among many to bring interested visitors closer to the effects of the ice age on the landscape. The members of the association Aufbruch Carwitz-Thomsdorf e. V. have made the design of the erratic boulder garden their task.
