David Blake (PI, CheMin instrument, SSX) conducted field geology with a group of 25 high school teachers in northern Arizona, June 24-28th. Blake’s participation was part of the CheMin team’s education outreach effort, which included Co-I’s Jack Farmer (Arizona State University) and Bob Downs (University of Arizona). Sheri Klug Boonstra and Jack Farmer of ASU organized the fieldwork. Sites of geological (and Astrobiological) interest that were visited included the Grand Canyon, Meteor Crater, Sunset Crater, and a side trip to the Lowell Observatory. The image above shows Blake conducting mineralogical analyses in the field using a commercial spinoff instrument to the CheMin instrument on Mars.
