The archipelago is about 285km long and 108km across, from the Barren Islands on the north to Chirikof Island and the Semidi Islands group on the south. The Archipelago contains 13,890km2 of land. The Kodiak Archipelago contains about 40 small glaciers, numerous streams and many species of land and marine animals. Much of its land is forested.
