A "Mulde" is a term used in geography to describe a depression or hollow in the landscape, often formed by natural processes such as erosion or glacial activity. These depressions can vary in size and shape and may contain water, forming lakes or ponds, or serve as natural drainage areas. In Germany, the term "Mulde" is also associated with the Mulde River, which flows through the states of Saxony and Saxony-Anhalt. The river is known for its scenic beauty and is a popular destination for outdoor activities like hiking and cycling along its banks.
