People have lived in the Warner Valley for more than 10,000 years. Evidence of Native American occupation includes
petroglyphs,
hunting blinds, flakes from
obsidian tools, and other material artifacts. By historic times, the Kidütökadö band of Northern
Paiute frequented the valley and the uplands of
Hart Mountain, the
fault block ridge to the east. The Euro-American
settler community of Plush developed in the late 19th century around sheep grazing and small cattle ranches.
Catholics from
Ireland found work here as shepherds; their surnames and their churches are part of the regional heritage. The name "Plush" is said to have derived from a mispronunciation of the word "
flush" during a 19th century
poker game played in the community. The Plush post office was established in 1888, and David R. Jones was the first postmaster. ==Geography==
