The Tanana River /ˈtænənɑː/ (Lower Tanana: Tth'eetoo', Upper Tanana: Tth’iitu’ Niign) is a 584-mile (940 km) tributary of the Yukon River in the U.S. state of Alaska.[n 1] According to linguist and anthropologist William Bright, the name is from the Koyukon (Athabaskan) tene no, tenene, literally "trail river".[7]

The river's headwaters are located at the confluence of the Chisana and Nabesna rivers just north of Northway in eastern Alaska.[8] The Tanana flows in a northwest direction from near the border with the Yukon Territory, and laterally along the northern slope of the Alaska Range, roughly paralleled by the Alaska Highway.[8] In central Alaska, it emerges into a lowland marsh region known as the Tanana Valley and passes south of the city of Fairbanks.[8]

In the marsh regions it is joined by several large tributaries, including the Nenana (near the city of Nenana) and the Kantishna. It passes the village of Manley Hot Springs and empties into the Yukon near the town of Tanana.[8]

Ice on the river accumulates each winter to an average maximum thickness of 43 inches (110 cm) at Nenana.[9] The Nenana Ice Classic, begun in 1917, is an annual guessing game about the date of the ice break-up.[9] In October or November, after the freeze has begun, a tripod is planted in ice in the middle of the river. The tripod is connected to an on-shore clock that stops when the tripod begins to move during the spring thaw. Over the years, the break-up date has varied from April 20 to May 20.[9] Betting on the exact time of the break-up takes the form of a lottery, called the Nenana Ice Classic.
