The Pyynikki Esker is the tallest longitudinal esker in the world, located in Pyynikki, Tampere, Finland. The ridge rises to a height of 160 meters above sea level and 80 meters above the surface of Lake Pyhäjärvi. The Pyynikki Esker belongs to the ridge formation that extends from South Ostrobothnia to Salpausselkä. The ridge formation continues west of the Pyynikki Esker as a rocky ridge known as the Pispala Esker (Pispalanharju) and Tahmela. To the east, after the settlement of Tampere, the ridge becomes the Kalevankangas esker, where there has been a cemetery by same name for almost 150 years. In Kangasala, the ridge formation continues as the four ridges called Kirkkoharju, Kuohunharju, Keisarinharju and Vehoniemenharju. The Pyynikki Esker, like longitudinal ridges, is mainly gravel and sand.
