The Wishram Indian Village Site, historically known as Nixlidix, is a location of profound cultural and historical significance situated along the Columbia River in Klickitat County, Washington. For centuries prior to Euro-American contact, this site served as the principal winter village of the Wishram (Tlakluit) people, a Chinookan-speaking group. Positioned strategically at the head of the Fivemile Rapids (historically known as the Long Narrows), Nixlidix functioned as the premier trading hub of the Pacific Northwest. Here, the distinct cultures of the Pacific Coast and the Columbia Plateau converged to exchange goods, including dried salmon, dentalium shells, bear grass, roots, and obsidian. This bustling marketplace not only facilitated a vast regional economy but also fostered rich linguistic and cultural exchanges, making it one of the most densely populated and ethnologically vital areas in pre-contact North America.

The historical importance of the site is further underscored by its documentation by early explorers, most notably the Lewis and Clark Expedition, which visited the village in 1805 and detailed its thriving population and large wooden plank houses. Beyond its ethnohistoric record, the surrounding area is renowned for its extraordinary concentration of indigenous rock art, including the iconic "Tsagaglalal" (She Who Watches) petroglyph, which reflects the deep spiritual and artistic traditions of the Wishram people. Although the construction of The Dalles Dam in 1957 inundated the rapids and much of the physical village site, the Wishram Indian Village Site remains a sacred ancestral locus and an invaluable archaeological resource that continues to provide critical insights into thousands of years of Indigenous maritime adaptation, trade networks, and cultural resilience.
