Virtual Field Trip to the basalts of the
Zuni-Bandera Malpais
El Malpais National Monument

As part of the 2000 Rockin' Around New Mexico Workshop, held in Grants, New Mexico, we visited several areas in the Zuni-Bandera Volcanic Field (which occupies much of the El Malpais National Monument) that show distinctive features of the physical volcanology of basaltic eruptions. These features include pahoehoe lava flows, a-a lava flows, a lava tube, an ice-bearing lava tube and a cinder cone. As part of the workshop, participants (see acknowledgements below) were tasked with taking photos and GPS locations of interesting features, and also preparing figure captions of the features that they photographed. This website is a result of their efforts. If you have any questions or comments about the material presented here, send an email to me (Nelia Dunbar).
