Tijeras Canyon (sometimes also referred to as Tijeras Pass) is a prominent canyon in the central part of the U.S. state of New Mexico. It separates the Sandia Mountains to the north from the Manzano Mountains to the south. (The two ranges can also be considered parts of one larger mountain chain.) Elevations along the bottom of the canyon range from 5,600 feet (1,700 m) to 7,000 feet (2,100 m) above sea level. The canyon drains to the west, into a large dry wash known as Tijeras Arroyo, which runs through Kirtland Air Force Base, passes just south of the Albuquerque International Airport, and then joins the Rio Grande. The arroyo heads at the historically important pass (approximately 7,040 feet (2,150 m)), and this pass and the entire canyon are traversed by Interstate 40, following the path of historic U.S. Route 66. (Route 66 originally passed through Santa Fe and entered Albuquerque from the North. In 1937 Governor Arthur Hannett re-routed the road away from Santa Fe and through Tijeras Canyon as revenge on politicians who he perceived had thwarted his re-election.)
