Although Pleistocene has been studied for many decades, there is still no unanimous opinion regarding the history of Pleistocene deposits. There are no geological features dating back to the Pleistocene, which complicates studying and analysing deposits and constitutes a major cause of disagreement. Another contentious issue is the stratigraphy of the Mid- and Late Pleistocene, namely, the identification of different-aged moraines of the Dnieper and Moscow Glaciation, as well as the Valdai glacial formations and their edges. Alongside boulder sandy clays, clays and loamy sands associated with the Pleistocene, the Quaternary deposits also include a wide range of rocks, whose origin is not always clear. Based on field observations, this article describes a number of denudations on the northern coast of the Sambia Peninsula, whose structure and genesis cannot be accounted for by the glacial theory.
