The volcanic landform that remains after the more resistant volcanic pipe is left behind following the erosion of most of the cone is called a volcanic neck or lava neck. This geological feature represents the hardened magma that solidified within the vent of a volcano. Over time, erosion removes the softer surrounding material, exposing the more durable neck. Examples of volcanic necks include formations like Shiprock in New Mexico.
