The reserve is located in the marginal zone of the last Viurms Glacier and is characterized by a young glacier relief with rare combination of moraine heights, lake-glacier plains and abundant deep hollows. The stages of the present surface natural evolution are observed in the reserve. The uniqueness of the reserve's territory is also determined by the fact, that it is situated on the plane watershed between the Black and the Baltic Seas and occupies a vast limno- and fluvioglacial plain.
