The article describes the discovery of ancient terraces along the Styr River valley in Ukraine. Researchers found five different terraces, with the main one being about 191-192 meters above the river. These terraces were formed during the Late Pleniglacial period, around 20,000 years ago. The main terrace has two layers - one made of alluvium from active river channels, and another made of sediment from when the river was inactive. The terraces are covered by a layer of loess, a type of wind-blown sediment. The absence of distinct soil layers suggests these terraces were formed during a cold period in Earth's history.
