Summarize this article for a 10 year old
The Delta River is an 80-mile (130 km) tributary of the Tanana River in the U.S. state of Alaska.[1] Its name in the Ahtna language is Saas Na’ [pronunciation?]. Fed by the Tangle Lakes of the Alaska Range, the river flows north to meet the larger river near Big Delta.[3] It is older than the Alaska Range, being formed before their uplift 30 million years ago.[4]
