Dall Island is an island in the Alexander Archipelago off the southeast coast of Alaska, just west of Prince of Wales Island and north of Canadian waters. Its peak elevation is 2,443 feet (745 meters) above sea level. Its land area is 254.0 square miles (657.9 km2), making it the 28th largest island in the United States. Dall is used economically for fishing and limestone quarrying.

The 2000 census recorded 20 persons living on the island.[1] Alaska Natives are known to have inhabited coastal caves on the island two to three thousand years ago.

Dall Island was first called Quadra, after Juan Francisco de la Bodega y Quadra, until 1879, when it was renamed in honor of naturalist William H. Dall.[2]

Cape Muzon, the southernmost point of the island, is the western terminus, known as Point A, of the A-B Line, which marks the marine boundary between the state of Alaska and the Canadian province of British Columbia as defined by the Alaska Boundary Treaty of 1903. This line is also the northern boundary of the waters known as the Dixon Entrance.


Dall Island is also an island used for its timber resource. The island houses many logging camps. Columbia Helicopters of Oregon is one of the main companies using the island for its timber.[citation needed]
