Tlingit and neighboring peoples. The greatest territory historically occupied by the Tlingit extended from the Portland Canal along the present border between Alaska and British Columbia, north to the coast just southeast of the Copper River delta in Alaska.
The Tlingits controlled the narrow stretch of coast and offshore islands that lie between the mainland glaciers and the open sea. Their territory extended the length of the Southeast Alaska mainland, but was no wider than 120 miles. Thousands of years ago, Tlingit Indians came down the Nass and Stikine rivers to occupy Southeast Alaska. A little later, Haida Indians began to push north from the Queen Charlotte Islands and displaced the Tlingits in some areas such, as around Howkan and Klinkwan.
