In an extraordinarily bold move, he then turned south and went around the island to M'Clure
Strait at its northern end, experiencing unprecedented danger from the heavy Beaufort Sea ice.
Some of the longest segments close the Gulf of Amundsen (99.2 n.m.), the Strait of M'Clure
(99.5 n.m.), the Lancaster Sound (51.3 n.m.), that is the western and eastern entrances of the Parry Channel.

(22) Between the islands lie a number of possible shipping routes connecting the Atlantic and Arctic Oceans (and later the Pacific Ocean), with the widest and deepest route running from Lancaster Sound through Barrow Strait into Viscount Melville Sound and onwards through M'Clure
Strait into the Beaufort Sea.

and Elijah Parish, Memoirs of the Rev.
The Northern (deep-water) route extends through Parry Channel and terminates in M'Clure
Strait, whereas the Southern (shallow-water) route extends from Baffin Bay to the Beaufort Sea via Lancaster Sound through eastern Parry Channel, then south along the eastern coast of Prince of Wales Island, and lastly westwards along the southern coasts of Victoria and Banks Islands into the Beaufort Sea.
Rae also reported that members of the expedition had likely resorted to cannibalism during their struggle for survival (M'Clure
and Rae, 1854).
Filtered locations were grouped into 13 geographic zones: EAG, western Amundsen Gulf, PAS, Coronation Gulf, Dolphin and Union Strait, Darnley Bay, Franklin Bay, Minto Inlet, Eastern Beaufort Sea, Prince of Wales Strait, Viscount Melville Sound, M'Clure
Strait, and McClintock Channel (Fig.
On average, sea ice is transported eastward in the northern reaches of the Beaufort Gyre, then southward down the western coast of the Canadian Arctic Archipelago along the Parry Islands, across M'Clure
Strait, and finally along the west coast of Banks Island before it turns west, following the northern continental coast and crossing the mouth of the Mackenzie River (Fig.
Areas near the edges of the CAA, including the periphery of the Western High Arctic, Amundsen Gulf, M'Clure
Strait, Lancaster Sound, Prince Regent Inlet and the Gulf of Boothia, were land fast for the shortest amount of time each year (Fig.
Stockton (1890) considered it unfortunate that Collinson's record was overshadowed by that of Robert M'Clure
(1807-73), who commanded HMS Investigator and abandoned his ship in Mercy Bay, Banks Island, but traveled on to make the first transit of the Northwest Passage.
On one occasion, while crossing M'Clure
Strait, Lieutenant Pim found his dogs quite satiated one morning, and assumed that they had caught and eaten large numbers of lemmings or had managed to kill a seal on their own account (Great Britain, 1955:658).
