The '''Northwest Passage''' is a sea passage between the [[Atlantic Ocean|Atlantic]] and [[Pacific Ocean|Pacific]] Oceans by way of the [[Arctic Ocean]] north of [[North America]]. Many [[explorer]]s, like [[John Cabot]] and [[Henry Hudson]], spent most of their lives trying to find the Northwest Passage, without success due to the polar icecap. However, the search for the Northwest Passage led to many great discoveries, such as [[Balboa]]'s discovery of the [[Pacific]], and the [[Lewis and Clark]] expedition (also to the Pacific, but much later).

The '''Northwest Passage''' is sea route of the North American continent from the Atlantic Ocean to the Pacific Ocean via Canada's Arctic Archipelago.  A dream of explorers and merchants since the 15th century to find the shortest route to the riches of the Far East, the Northwest Passage was successfully navigated in 1906, after years of hardship and tragedy in one of the world's harshest environments.

 

The Northwest Passage begins in Baffin Bay, an arm of the Atlantic Ocean between Greenland and Baffin Island, some five hundred miles north of the Arctic Circle. West into Lancaster Sound north of Baffin Island the route splits: a northern route follows the waterways south of Devon, Bathurst, and Melville islands before turning south into Prince of Wales Strait between Victoria and Banks islands and entering into Admundsen Gulf; the southern route enters Peel Sound west of Somerset Island, and enters Queen Maud and Coronation gulfs, and ultimately Admundsen Gulf.  The route then continues along the north shore of Canada and Alaska (Beaufort Sea), then enters the Bering Strait for the Pacific Ocean.  From its eastern entry to the Beaufort Sea the route is about 900 miles long.

 

The major hazard for ships sailing the route is free-floating ice.  Within Baffin Bay icebergs calved from Greenland's glaciers drift south by the thousands; much of the central portion of the route as well as the Beaufort Sea suffers from the polar ice cap pushing ice south; this can funnel a mass of ice through the waterways within the archipelago as well as the Bering Strait during much of the year.  Many ships that have sailed within this area have found themselves trapped by the ice and forced to "winter-over" until the spring thaw.

 

Prior to Columbus, trade goods came to Europe from China and India via overland routes like the Silk Road, which had its terminus in Constantinople.  The conquest of that city as well as much of the Middle East by the Ottoman Turks in the mid-15th century prompted the first series of explorations westward by sea. Before the 1490s had ended it had been realized that the new lands found by Columbus were not part of the Far East; this prompted Portuguese navigator Vasco da Gama in 1498 to sail to India by way of a southern voyage around Africa, and another Portuguese explorer, Ferdinand Magellan, to sail to what was then called the East Indies (Indonesia) by going around the southern tip of South America and into the Pacific Ocean.

 

It was also realized that a northern route to the Far East would be shorter in terms of distance (about 8,000 miles) and time.  John Cabot was sent by King Henry VII in the first search for a northwestern passage, reaching Newfoundland in 1496, and making an attempt for Japan in a second, ill-fated expedition in 1498.  Exploration for the route would be in small steps; the Frenchman Jacques Cartier would chart the eastern Canadian coast and St Lawrence River; Sir Martin Frobisher explored the northern areas around Baffin Bay and attempted a colony at Frobisher Bay; and Henry Hudson would search for the passage in 1610, entering the vast bay which bears his name before being cast adrift by a mutinous crew in 1611.

 

Two centuries of trial and error at sea by explorers John Davis (1585), William Baffin (1615, 1616), Sir John Ross (1829-33), Sir William Parry (1819), Frederick William Beechey (1825-28), and Sir George Back (1836-37) did much to add to the knowledge of the Canadian Arctic; this was supplemented by overland explorers Henry Kelsey (1688-91), Samuel Hearne (1770-72), and Sir Alexander Mackenzie (1789) as they explored much of Canada west of Hudson Bay to the Arctic.
