+Klû’kătät+ (Shahaptian stock).—_Synonyms_: Clickahut, Clickitat, Klikatat, Qwû′lh-hwai-pûm, Weyehhoo, Whulwhypum. The name by which this tribe is commonly known is from the Wasko language and signifies “beyond (the mountain)”—that is, east of the Cascade range—with reference to the Chinookan tribes on the lower Columbia. The same name was also at times extended to the Yakima. They call themselves Qwûlh-hwai-pûm, “prairie people;” from _qwûlh-hwai_, “prairie,” and _pûm_, “people,” referring particularly to their occupancy of Camass prairie. They formerly occupied the southern slopes of Mount Adams and Mount Helens, with the country of Klikatat and Lewis rivers, in the present Klickitat and Skamania counties, Washington. East of them were the Yakima and west were the Salishan and Chinookan tribes. At one time they lived farther east, but were driven west by the Cayuse. (_Stevens._) About sixty years ago they crossed the Columbia and overran the Willamet country, and even penetrated as far south as the Umpqua, but afterward withdrew again to their proper country. Although but a small tribe, they were aggressive and enterprising and were the trade medium between the tribes west of the mountains and those east. They joined in the Yakima treaty of 1855 and are now chiefly on Yakima reservation, but a few are still on White Salmon river, in Klickitat county. Their number is unknown. The Taitinapam and Topinish speak the same language and may be considered as branches of this tribe. +Qa′pnĭsh-‛lĕma+ or +Topinish+ (Shahaptian stock).—A small tribe on Topinish river in Yakima county, Washington, within the present limits of the reservation. They speak the Klûkatät language. The name signifies “people (_‛lĕma_) of the trail coming from the foot of the hill.” +Taitinapam+ (Shahaptian stock).—_Synonym_: Tai-kie-a-pain (misprint). A small tribe speaking the Klûkatät language, formerly living on the western slopes of the Cascade mountains, between the heads of Lewis and Cowlitz rivers, in Skamania county, Washington, being the westernmost tribe of Shahaptian stock. If any are left, they are probably incorporated with the Klûkatät on Yakima reservation. They never had official recognition. +Chämnä′pûm+ (Shahaptian stock).—_Synonyms_: Chimnahpum, Chimnapoos, Cuimnapum. A tribe which occupied the bend of the Columbia below Yakima river, together with the country on the lower Yakima, chiefly in the present Yakima county, Washington. They are the Chimnahpum of Lewis and Clark, and speak a dialect of the language of the Pä′lus and Wanapûm, with which tribes the few survivors are incorporated. A few are also still living on the west side of the Columbia, opposite Pasco. The name is of their own language and means “people (_pûm_) of Chämnä′,” their old village about opposite Wallula.
