Southern and central Finland contain extensive mosaics of forest and lakes. The broken southwest coast opens into an archipelago, while the Gulf of Bothnia and Gulf of Finland help orient a regional view. These water bodies provide stronger anchors than a forested crop on its own.
Checking the location
Compare the pattern with Sweden and northwestern Russia, which also have glaciated terrain and many lakes. A small patch of water and conifer forest may remain ambiguous. Trace a shoreline or a connected lake system to a named feature before deciding. Snow and lake ice can hide the distinctions you would use in a summer image.
