The Albuquerque Volcanoes are three cinder cones that lie west of Albuquerque, New Mexico and North of Interstate Highway 40. The are all geologically young, as young as 140,000 years before present, according to this website. They are primarily cinders (or scoria) with some spatter and flows around the vent area. These volcanoes and the underlying, older basalt flows are the result of fissure eruptions.
From downtown Albuquerque, which lies in the Rio Grande Valley, these volcanoes form part of the western skyline.
