Narbona Pass (formerly Washington Pass) is a pass through the natural break between the Tunicha and Chuska Mountains, an elongated range on the Colorado Plateau on the Navajo Nation.A paved road, New Mexico Highway 134, crosses the range through Narbona Pass, connecting Sheep Springs to Crystal.Known in the Navajo Language as So Sila (Twin Stars), the pass was lately named in English for Colonel John M. Washington in 1859. He was a New Mexico military governor who led an expedition into Navajo country in 1849 in which he was accused of walling up a Navajo Spring, and whose troops later shot Navajo leader Narbona.
