The Copper River or Ahtna River (/ˈɑːtnə/), Ahtna Athabascan ‘Atna’tuu ([ʔatʰnaʔtʰuː]), "river of the Ahtnas",[1] Tlingit Eeḵhéeni ([ʔìːq.híː.nì]), "river of copper",[2][3] is a 290-mile (470 km) river in south-central Alaska in the United States. It drains a large region of the Wrangell Mountains and Chugach Mountains into the Gulf of Alaska.[4] It is known for its extensive delta ecosystem, as well as for its prolific runs of wild salmon, which are among the most highly prized stocks in the world.[5] The river is the tenth largest in the United States, as ranked by average discharge volume at its mouth.[6]
