Summary

The Kvarken Archipelago (Finland) and the High Coast (Sweden) are situated in the Gulf of Bothnia, a northern extension of the Baltic Sea. The 5,600 islands of the Kvarken Archipelago feature unusual ridged washboard moraines, ‘De Geer moraines’, formed by the melting of the continental ice sheet, 10,000 to 24,000 years ago. The Archipelago is continuously rising from the sea in a process of rapid glacio-isostatic uplift, whereby the land, previously weighed down under the weight of a glacier, lifts at rates that are among the highest in the world. As a consequence islands appear and unite, peninsulas expand, and lakes evolve from bays and develop into marshes and peat fens. The High Coast has also been largely shaped by the combined processes of glaciation, glacial retreat and the emergence of new land from the sea. Since the last retreat of the ice from the High Coast 9,600 years ago, the uplift has been in the order of 285 m which is the highest known ''rebound''. The site affords outstanding opportunities for the understanding of the important processes that formed the glaciated and land uplift areas of the Earth''s surface.

High Coast / Kvarken Archipelago

The High Coast / Kvarken Archipelago is a UNESCO World Heritage site located in Finland. It is situated in the Gulf of Bothnia, between the cities of Vaasa in Finland and Umeå in Sweden. The coordinates of the site are N63 17 60 E21 18 0.

History

The High Coast / Kvarken Archipelago has a rich history that dates back thousands of years. The area has been inhabited since the Stone Age, and evidence of human presence can be found in the form of ancient rock paintings and archaeological sites.

During the Viking Age, the region became an important trading route, connecting the Baltic Sea with the inland areas of Scandinavia. The archipelago provided sheltered waters for ships and served as a hub for maritime trade.

In the 18th and 19th centuries, the High Coast / Kvarken Archipelago played a significant role in the timber industry. The area was known for its vast forests, and timber was exported to various parts of Europe. The logging activities had a profound impact on the landscape, shaping the unique coastal features that exist today.

Current State

The High Coast / Kvarken Archipelago is renowned for its exceptional geological features. The site is characterized by a phenomenon known as "post-glacial rebound," which refers to the rising of landmasses that were previously depressed by the weight of glaciers during the last Ice Age.

This rebound has resulted in a distinctive landscape, with a series of islands and skerries emerging from the sea. The archipelago consists of over 5,600 islands and islets, forming a complex and diverse ecosystem. The islands are covered in lush forests, and the surrounding waters are home to a wide range of marine life.

The site is also known for its unique geological formations, such as "De Geer moraines" and "ribbed moraines." These formations were created by the movement of glaciers and are considered significant examples of glacial landforms.

The High Coast / Kvarken Archipelago is not only a geological marvel but also a haven for biodiversity. The area supports a variety of plant and animal species, including rare and endangered ones. It serves as an important breeding ground for birds and provides a habitat for seals and other marine mammals.

The site is managed jointly by Finland and Sweden, with both countries working together to preserve and protect its natural and cultural heritage. Conservation efforts focus on maintaining the delicate balance of the ecosystem and promoting sustainable tourism.

Visitors to the High Coast / Kvarken Archipelago can explore the islands and enjoy activities such as hiking, boating, and birdwatching. The site offers a unique opportunity to witness the ongoing geological processes that have shaped the region over thousands of years.

In conclusion, the High Coast / Kvarken Archipelago in Finland is a UNESCO World Heritage site of immense geological and ecological significance. Its rich history, unique landscape, and diverse wildlife make it a must-visit destination for nature enthusiasts and those interested in understanding the Earth's dynamic processes.
