Tijeras Canyon (sometimes also referred to as Tijeras Pass) is a prominent canyon in the central part of the US state of New Mexico. Tijeras Canyon is often referred to by locals as the I-40 Canyon after the major highway that traverses it, linking Albuquerque and points east. 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. It heads at a historically important pass, 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.
