The Nastapoka Islands ( French Îles Nastapoka ) form a 165 km long chain of islands in the east of Hudson Bay . The nearly 5 km wide Nastapoka Sound separates the islands from the west coast of the Labrador Peninsula . The island chain consists of 18 larger islands. These reach heights of up to 115 m and widths of up to 4 km.
Politically, the islands belong to the Qikiqtaaluk region of the Canadian territory of Nunavut . It was previously believed that the island's arc could have been created by a meteorite impact . However, no breccia was found on the islands, so this thesis was rejected. Today it is believed that the striking shape of an arc of a circle was created by the collision of two mainland cores.
