Christy Caudill, Deputy Chief in the AZGS Geoinformatics Section was showcased in the February 2 issue of Eos, the weekly news magazine from the American Geophysical Union, in a full page "postcard from the field."
Christy's caption is, "I’m in the Artillery Mountains using a portable X-ray fluorescence analyzer to examine clastic sedimentary rocks - conglomerate and sandstone
- or evidence of potassium, sodium, and calcium mobilization by
low-temperature diagenetic alteration associated with basin brines. A
rare cloudy day here in western Arizona."
