Western US 2005

In summer 2005, I drove from Iowa City to Utah to meet up with Ingrid who was teaching Summer Field Camp in Park City. We went down to south-west Utah to collect samples from the Black Rock Desert Volcanic Field (near Filmore) for an NSF-funded project to study crustal assimilation processes. We then went up to Corvallis to do some analytical work with Adam Kent at Oregon State University. During the trip home, we managed to see several excellent exposures of the Columbia River flood basalts.
