Extinct Shiprock
A rock formation rising nearly 1,800 feet (550 m) above the high-desert plain on the Navajo Nation; the erosional remnant of the throat of an extinct volcano.
It is located in the center of the Ancient Pueblo People or Ancestral Puebloan civilization, a prehistoric Native American culture of the Southwest United States.
Shiprock is considered as an extinct volcano since it is not currently erupting and which is not considered likely to erupt in the future.
