Amboy Crater
National Natural Landmark

Amboy Crater, formed of ash and cinders, is 250 feet high
and 1500 feet in diameter. The crater is in one of the youngest
volcanic fields in the United States. Six distinct periods of
eruptions created the resulting nested group of volcanic cinder
cones encompassing 24 square miles. Volcanic activity started
an estimated 6000 years ago with the last period of eruptions
occurring as recently as 500 years ago. Amboy Crater's recent
origin and its near-perfect shape led to its designation as a
National Natural Landmark in 1975. Climb to the rim of the
crater to see an outstanding view of the associated lava field
and surrounding desert area.
