Agai-deka

The Agai-deka, or Agaidika, are the Salmon Eaters of the Northern Shoshone, better known as the Lemhi Shoshone after the Lemhi River valley in Idaho where they made their main home, together with the upper Salmon River. Speaking Shoshone, a Numic language, they built their diet around salmon and trout runs, supplemented by camas root and gooseberries, and in the nineteenth century rode out on to the plains on buffalo hunts.

Their bands were fluid and heavily intermarried with the Bannock. The most famous child of the band was Sacagawea, born into it around 1788, who guided the Lewis and Clark Expedition.

The expedition met her people at the Three Forks of the Missouri in 1805. Through the early nineteenth century the Agai-deka rode with the Flathead as allies against the Blackfeet.
