Lankakivi

Lankakivi is a type of geological formation found primarily in Estonia. These formations are characterized by their unique elongated shape, often resembling a stone or boulder that has been stretched. The name "Lankakivi" itself is Estonian and translates roughly to "slope stone" or "long stone," referencing its typical appearance and sometimes its location on inclines.

These stones are usually composed of limestone or sandstone and are a result of glacial erosion and weathering processes that have occurred over thousands of years. The glaciers, in their movement across the land, would have carried and abraded rocks, shaping them into distinctive forms. Subsequent freeze-thaw cycles and other environmental factors further contributed to their elongated and sometimes striated appearance.

Lankakivi formations are not found in large quantities and are considered a notable feature of the Estonian landscape. They are often found in areas with thin soil cover and exposed bedrock. While their exact geological origins are subject to ongoing study and interpretation, they are a testament to the powerful geological forces that have shaped the Baltic region. They are sometimes observed in parks or protected natural areas, contributing to the scenic beauty of these locations.
