There's a fascinating profile on Mineweb.com of Reno-based geologist Alex Chaihorsky, who is working in Afghanistan for the USGS and Defense Dept, assessing the nation's mineral resource potential. The term 'combat geology' refers to working in situations where the geologist "goes into the field with the possibility that he or she--and the security detail protecting him or her--could be shot and killed in an instant."
Here in Arizona, AZGS geologists are constrained from working in certain areas near the border with Mexico over concerns about encountering drug smugglers. We have taken additional safety measures, including working in teams, staying in touch with local and border authorities, and providing geologists with radios, and soon, satellite phones for remote areas.
