Dall Island is an island in the Alexander Archipelago off the southeast coast of Alaska ( Panhandle ), west of Prince of Wales Island and north of the Canadian Waters. The highest point is 745 m. With an area of 657.9 km², it ranks 28th in the list of the largest islands in the United States. The highest mountain is Thunder Mountain in the northern part of the island, with a height of 948 meters.
The United States Census 2000 reported 20 residents on the island. The indigenous people of Alaska are known to inhabit the coastal caves 2,000 to 3,000 years ago.
The island is used for fishing, forestry and as a limestone quarry.
The island was formerly called Quadra , named after Juan Francisco de la Bodega y Quadra , until it was renamed in 1879 in honor of the naturalist William Healey Dall .
Cape Muzon, the southern tip of the island, is the western end point, known as Point A , of the AB line that marks the maritime border between the US state of Alaska and the Canadian province of British Columbia under the Alaska Boundary Treaty of 1903. This line is also the northern limit of the strait called Dixon Entrance .
