Without the hard, unyielding primary rock – we would not have had the archipelagos along the coasts of Sweden and Finland. Finland wouldn’t have been “The land of a thousand lakes” and Sweden’s water-filled rift valleys would not exist if it hadn’t been for bedrock. We who live in Sweden and Finland have ever-present rocky hills and granite cliffs. We don’t think about it – it’s completely natural.https://www.balticsealibrary.info/essays/item/162-nature-in-the-history-of-the-baltic.html
