Raton Pass in the 1960s 16th Anniversary

Raton Pass is a 7,834 ft (2,388 m) elevation mountain pass on the Colorado–New Mexico border in the western United States. It is located on the eastern side of the Sangre de Cristo Mountains between Trinidad, Colorado and Raton, New Mexico, approximately 180 miles (290 km) northeast of Santa Fe. Raton is Spanish for "mouse". The pass crosses the line of volcanic mesas that extends east from the Sangre de Cristo Mountains along the state line, and furnishes the most direct land route between the valley of the Arkansas River to the north and the upper valley of the Canadian River, leading toward Santa Fe, to the south. The pass now carries Interstate 25 and railroad tracks. The pass is a historically significant landmark on the Santa Fe Trail, a major 19th-century settlement route between Kansas City, Missouri and Santa Fe. It was designated a National Historic Landmark in 1960 for this association.
