Northwest Passage
19th century

In the first half of the 19th century, some parts of the Northwest Passage (north of the Bering Strait) were explored separately by many expeditions, including those by John Ross, Elisha Kent Kane, William Edward Parry, and James Clark Ross; overland expeditions were also led by John Franklin, George Back, Peter Warren Dease, Thomas Simpson, and John Rae. In 1826 Frederick William Beechey explored the north coast of Alaska, discovering Point Barrow.

Sir Robert McClure was credited with the discovery of the Northwest Passage in 1851 when he looked across McClure Strait from Banks Island and viewed Melville Island. However, this strait was not navigable to ships at that time. The only usable route linking the entrances of Lancaster Sound and Dolphin and Union Strait was discovered by John Rae in 1854.
