BackgroundAn older volcanic episode in the field comprises the vents along the Chain of Craters, which are dated to about 3.8-3.7 million years ago. The present-day episode began about 1.7 million years ago and has formed an extensive lava flow field known as El Malpais.
The only other dated flow of Holocene age of the Zuni-Bandera field originated from Bandera Crater about 10,000 years ago. An earlier flow, the massive Pleistocene Fence Lake lava flow, traveled as far as 90 km to the west.
