The Iditarod River is a 325miles tributary of the Innoko River in the U.S. state of Alaska.[2] The river begins north of Chuathbaluk and the Russian Mountains and flows northeast and then west to meet the larger river near Holikachuk.[3]
Iditarod is an Anglicization of the Deg Hit’an (Athabascan) name for the river, Haiditirod or Haidilatna,[2] which is probably an English version of the name of a village on the river, that may have corresponded with the village called Iditarod in the 1900s.
