Capulin Mountain National Monument (1)

Historical marker location:

US 64/87, Capulin, New Mexico

( At junction with NM Highway 325)

An outstanding example of an extinct volcanic cinder cone, Capulin Mountain was formed as early as 10,000 years ago. In cinder cones, lava pours from cracks in the base rather than over the top. Capulin itself was the escape hatch for gases that blew lava fragments into the air where they solidified and landed red hot on the cone.
