The Susitna River [ su'sɪtnə ] is a 503 km long river in the U.S. state of Alaska.
The river rises on the Susitna Glacier on Mount Hayes ( 4216 m) in the Alaska Range and flows on the west side of the Talkeetna Mountains along. In Trapper Creek rivers flow Chulitna River and Talkeetna River in the Susitna, which is navigable from there. Eight kilometers north of Susitna opens the Yentna River in the Susitna River. Approximately 40 km west of Anchorage the Susitna River flows finally into the Cook Inlet.
Together with the Matanuska River is the Susitna River eponymous for the Matanuska- Susitna Borough and the Matanuska- Susitna Valley ( Matanuska- Susitna Valley English, short Mat-Su ) north of Anchorage, one of the most densely populated regions of Alaska.
