The Kvarken Archipelago - FINLAND - UNESCO #898
This is the second official card I've got from Finland today and once again, to my great pleasure, the sender choosed a UNESCO site postcard for me, this time the Kvarken Archipelago, part of a site that also includes High Coast in Sweden. Thank you so much Sini for picking this awesome card and an amazing stamp that celebrates Postcrossing - I love it! Ok now, about the collection, 172 down, 809 to go. This postcard took 4 days to arrive!
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.
