lava butte

Encyclopedia Article


Also known as volcanic plugs or necks, lava buttes form when magma hardens within a vent of an active volcano. Erosion can remove the surrounding rock, leaving the erosion-resistant plug behind, producing a distinctive, upstanding landform.

Shiprock, New Mexico, is one example of a lava plug.
