After many successful field days in sedimentary strata, yesterday we had a day of exploration. We traveled with the Ohio State field camp to Fillmore, Utah, to investigate the Black Rock Desert. Specifically, we spent our time in the Ice Springs Volcanic Field, which provides the youngest volcanic activity in the Black Rock Desert (~600 years old).
We thought that the Icelandic Team would be especially interested in some of our photos, since basalt seems to be near and dear to their hearts.
Jesse Davenport, studious as ever, is listening intently to a lecture on the Ice Springs Volcanic Field. The rough, brecciated aa of the field is behind him.
Elyssa Krivicich (left, '09) and Elizabeth Deering (right) proudly display the Utah basalt. The Red Dome cinder cone is in the background. Hey Dr. Pollock and Becky Alcorn (our Icelandic Team)...do you like it?
This is a photo of a cross-section through the Red Dome cinder cone, which is quarried for landscaping purposes. Take a look at the pronounced bedding that is due to successive pulses of air-fall deposits. We collected volcanic blocks and bombs both at the base of the cinder cone and then at the very top.
The view from the top of the Red Dome cinder cone is amazing. You can see a smaller cinder cone nearby. In the distance, you can see Pahvant Butte. If you look close enough, the ancient shorelines of Lake Bonneville are exposed at the base of Pahvant Butte.
