Estonia - Baltic Klint

The North-Estonian limestone escarpment is part of a more extensive landform -the Baltic Klint. The total length of the Baltic Klint is 1100-1200 km; of that 250 km are in mainland Estonia. The limestone cliff begins from the western coast of the Island of Oland in Sweden. From the northern coast of the island it extends under the sea to the Island of Osmussaar and continues on the Pakri Islands. The mainland stretch of the klint starts on Pakri Peninsula. The klint runs through Estonia to Russia where it disappears under younger, Devonian rocks on the southern shore of Lake Ladoga. The Klint is at its highest (55.6 m a.s.l.) at Ontika in eastern Estonia. The North-Estonian Klint enables to study the rocks formed more than 500 million years ago. Starting from the Island of Osmussaar and ending in the Ida-Viru County the evolution of the Cambrian and Ordovician sea and biota may be traced during the course of about 100 million years.
