Liksiyu

Liksiyu is a name of the Cayuse people, whose homeland extended across the upper Umatilla and Walla Walla river country and the Blue Mountains. Skilled horse breeders, the Cayuse used horses to travel, hunt and exchange goods over a wide area of the Columbia Plateau. In 1836 the missionaries Marcus and Narcissa Whitman established a mission in the Walla Walla Valley with the permission of Hiyuumtipin, a Cayuse headman. Their arrival brought a new and consequential presence into the valley.
