Putulik, formerly Hat Island, is a small (about) uninhabited island located in the Kitikmeot of Nunavut, Canada. The island is situated in Victoria Strait (Queen Maud Gulf) approximately southeast of Victoria Island and southwest of King William Island. The Requisite Channel separates the island from Amundsen Island, the larger of the Nordenskiöld Islands.
Hat Island (CAM-B) is a former Distant Early Warning Line and current North Warning System site[1] The Canadian government's Contaminated Sites directorate has determined Hat Island to be a contaminated site in need of future remediation.[2]
Another smaller Hat Island is also in Nunavut.
