Joseph Whidbey leads an expedition to search for the Northwest Passage near Juneau, Alaska.

Joseph Whidbey FRS was a member of the Royal Navy who served on the Vancouver Expedition 1791–95, and later achieved renown as a naval engineer. He is notable for having been the first European to discover and chart Admiralty Island in the Alexander Archipelago in Alaska in 1794.

The Northwest Passage (NWP) is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, near the northern coast of North America via waterways through the Arctic Archipelago of Canada. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP). The various islands of the archipelago are separated from one another and from mainland Canada by a series of Arctic waterways collectively known as the Northwest Passages, Northwestern Passages or the Canadian Internal Waters.

Juneau, officially the City and Borough of Juneau, is the capital of the U.S. state of Alaska, located along the Gastineau Channel and the Alaskan panhandle. Juneau was named the capital of Alaska in 1906, when the government of what was then the District of Alaska was moved from Sitka as dictated by the U.S. Congress in 1900. On July 1, 1970, the City of Juneau merged with the City of Douglas and the surrounding Greater Juneau Borough to form the current consolidated city-borough, which ranks as the second-largest municipality in the United States by area and is larger than both Rhode Island and Delaware.
