city, seat (1897) of Colfax county, northeastern New Mexico, U.S. It lies at the southern end of Raton Pass (7,834 feet 【2,388 metres】 above sea level) in the Sangre de Cristo Range, near the Colorado state line. Located on the old Santa Fe Trail and settled in 1871, it was used as a watering place by cattlemen. The town, initially called Willow Springs, was laid out in 1880 after the arrival of the Santa Fe Railroad and was named Raton (Spanish: “Mouse”) for a nearby lava-capped mountain that was inhabited by many small rodents; the area is subject to periodic outbreaks of bubonic plague. Raton developed as a shipping point for coal and livestock.
