Geography of southeast Alaska

Southeast Alaska has a land area of 35,138 square miles (91,010 km²), comprising much of the Alexander Archipelago. The largest islands are, from North to South, Chichagof Island, Admiralty Island, Baranof Island, Kupreanof Island, Revillagigedo Island and Prince of Wales Island. Major bodies of water of Southeast Alaska include Glacier Bay, Lynn Canal, Icy Strait, Chatham Strait, Stephens Passage, Frederick Sound, Sumner Strait, and Clarence Strait.

The archipelago is the northern terminus of the Inside Passage, a protected waterway of convoluted passages between islands and fjords, beginning in Puget Sound in Washington state. This was an important travel corridor for Tlingit, Haida, and Tsimshian Native peoples, as well as gold-rush era steamships. In modern times it is an important route for Alaska Marine Highway ferries as well as cruise ships.
