town, San Juan county, northwestern New Mexico, U.S. Lying on the vast Navajo reservation, the town, originally called Needles, was founded in 1903 as a centre of tribal government. It served as such until 1938, when the Navajo nation established its capital at Window Rock, Arizona. The town takes its name from Ship Rock, a volcanic rock located 10 miles (16 km) to the southwest. This rock rises 1,400 feet (420 metres) from the desert; in Navajo the peak is called tse bida'hi, “winged rock,” and it figures prominently in Navajo mythology. Pop. (1990) 7,687; (2000) 8,156.
