The West Mesa (New Mexican Spanish: Atrisco) is an elevated landmass lying west of the Rio Grande, and the westside of Albuquerque, stretching from the South Valley northward to Bernalillo and Rio Rancho in the U.S. state of New Mexico.
The eastern edge of the West Mesa is defined by an escarpment that borders the Rio Grande floodplain. The West Mesa also serves as the easternmost extent of the Colorado Plateau in this region. The western edge of the mesa is the Rio Puerco near the Laguna Pueblo about 20 miles (32 km) west of Albuquerque. A large portion of the West Mesa is part of Petroglyph National Monument. It is bisected by Interstate 40 and Historic Route 66. Atrisco Vista (previously named Paseo del Volcan) (NM 347) runs north-south on the West Mesa, connecting I-40/US-66 to Double Eagle II Airport.
