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.
Klickitat County, Washington
Klickitat County was created out of Walla Walla County on December 20, 1859. Samuel Hill was an early promoter of the area, promoting better roads and building local landmarks such as a war memorial replica of Stonehenge (Maryhill Stonehenge) and a mansion that would become the Maryhill Museum of Art. The Sam Hill Memorial Bridge across the Columbia River is named after him.
