Klickitat people
In the early 1850s, the Klickitat Tribe raided present-day Jackson County, Oregon from the north and settled the area. Modoc, Shasta, Takelma, Latgawas, and Umpqua Indian tribes had already lived within the present boundaries of that county.
Whilkut
The Whilkut also known as "Redwood Creek Indians" or "Mad River Indians" were an Athapaskan tribe, speaking a dialect similar to the Hupa and Chilula, who inhabited the area on or near the upper Redwood Creek and along the Mad River except near its mouth, up to Iaqua Butte, and some settlement in Grouse Creek in the Trinity River drainage in Northwestern California, before contact with Europeans.
