Klikitats, a roving tribe of Indians, north of the Columbia river and east of the Cascade mountains, composed of five bands, and numbering between 2,000 and 3,000. They are great gamblers for hyaqua, or shell money, and are restless and troublesome. They joined the Yakimas, with whom they are closely united, in the war of 1855, killed the agent Bolen, and took part in the surprise of Step-toe, but were defeated by Wright. They were soon after placed on White Salmon reservation, and are now on the Yakima reservation near Fort Simcoe, Washington territory, and are regarded as part of the Yakima nation.
