Lumparn (fi. Lumpari) is a large bay devoid of islands in the main island of Åland, Finland, bordered by Sund to the north, Lumparland to the east, Lemland to the south and Jomala to the west.

Description

Most of the bay fills a nine kilometer wide

shatter cones have been discovered in the southwestern part of the bay. The remains of the crater are filled with sediments, between Pleistocene sediments and crushed rapakivi granite bedrock there is a layer of Paleozoic (Ordovician) limestones. This makes Lumparn one of the few places in Finland where fossils
have been found.

The bay has also previously been referred to as Lumpari

Research Institute for the Languages of Finland does not list Lumpari as in current usage.[3]
