River Delta

The Delta River is an 80-mile tributary of the Tanana River in the U.S. state of Alaska. Its name in the Ahtna language is Saas Na’. Fed by the Tangle Lakes of the Alaska Range, the river flows north to meet the larger river near Big Delta. It is older than the Alaska Range, being formed before their uplift 30 million years ago.
