Geochemistry and geophysics field maps used during the USGS 2011 field season in southwest Alaska Geochemistry and geophysics field maps used during the USGS 2011 field season in southwest Alaska
The US Geological Survey (USGS) has been studying a variety of geochemical and geophyscial assessment techniques for concealed mineral deposits. The 2011 field season for this project took place in southwest Alaska, northeast of Bristol Bay between Dillingham and Iliamna Lake. Four maps were created for the geochemistry and geophysics teams to use during field activities.
