The Shasta Costa (also known as the Chasta Costa, Shastacosta, Chastacosta, Shastao-Skoton, Shista-Kkhwusta 1 or Shistakwasta 2), are a Native American tribe from southwestern Oregon, who originally lived on the Rogue River and its tributaries, or, more precisely, on the "Lower Illinois River and the Rogue River between present-day Agness and Foster Bar."3 They were classified as Rogue River Indians for the purposes of treaty negotiation. One of their villages, Tlegetlinten, was located near Agness, and was eventually "occupied by Euro-American settlers."4
In January 1856, two miners near the junction of the Illinois and Rogue Rivers were killed. It was never known if the miners were killed by the Indians living in the area or if they were killed by other miners in the area. The military sent Lieutenants John Chandler and John Drysdale with seventeen men to the fork of the Illinois and Rogue Rivers to persuade the "Shis-ta-koos-tee" ... band to leave their settlement and move to the coast to avoid further disruptions between miners and Indians. According to Beckham, "When the young lieutenants were not able to induce the peaceful bands to leave their plank houses for the uncertainties of life near the white settlements, the troops fell back to the towns at the mouth of the Rogue River."4
