The strait separates Nuussuaq Peninsula in the northeast from Qeqertarsuaq Island in the southwest. The strait waterway connects inner Disko Bay in the southeast with Baffin Bay in the northwest. Qeqertarsuatsiaq Island is located in the northeastern mouth of the strait, where it opens into Baffin Bay. At the southeastern end, the large Alluttoq Island is located in the outlet of the strait, at the confluence with Disko Bay. Archaeological excavations in Qilakitsoq on the northeastern shore revealed the existence of an ancient
Baffin Island at a similar latitude. Sea ice surrounds the island for most of the year, and only disappears completely from the north coast for short unpredictable periods from mid- to late June until the end of September. Most of Baffin Island lies above the Arctic Circle and all the communities from Pangnirtung northwards have polar night in winter and the midnight sun in summer. The eastern community of Clyde River has twilight instead of night from April 26 until May 13, continuous sunlight for 2½ months from May 14 to July 28, then twilight instead of night from July 29 until
