Cabezon Peak is a large volcanic plug that is a prominent feature in northwestern New Mexico. It rises to 7,785 feet in elevation. Cabezon Peak is two miles south of the old ghost town of Cabezon and the Rio Puerco. This volcanic neck is formed of basalt and is part of the Mount Taylor volcanic field. A volcanic neck or plug is formed when magma from an existing volcano solidifies in the pipe or neck and the surrounding sediment is eroded away.
