2021 Call for Field Trip Logs, Papers, and Conference Volunteers

Join us for the 2021 TRGS Field Conference at Idaho State University (ISU) Geosciences’ Lost River Field Station near Mackay, Idaho (https://www.isu.edu/geosciences/fieldcamp/lost-river-field-stationlocation/). We welcome proposals for field trips, posters, and papers about any aspect of the geology in and around the Lost River Valley. Field guides, abstracts, and papers will be published in Northwest Geology, the annual publication of TRGS. Please contact Dave Pearson (pearson@isu.edu) by March 15, 2021 with your proposed titles. Submission guidelines are posted at https://www.trgs.org/northwest-geology. All manuscripts and road logs must be received by April 15, 2021.

The Lost River Field Station, located in the Big Lost River Valley, is nestled at the foot of Borah Peak, the highest mountain peak in Idaho. The region is home to spectacular landscapes and a tremendous diversity of geology: folded and faulted sedimentary rocks, ductilely deformed Archean and Proterozoic metamorphic and igneous rocks in the Pioneer metamorphic core complex, fossiliferous sedimentary
rocks, ancient and active faults, Cenozoic volcanic and plutonic rocks and related mineralization, recent
alpine glaciation, and Quaternary geology. Want to help with the conference? Contact Paul Link at linkpaul@isu.edu.
