On this trip, GSOC participants got to view some sedimentary, metamorphic and very very old rocks; a bit of a departure from our normal field trip fare. For this, we had to journey some 300-400 miles ENE from Portland to the NE Washington/Idaho panhandle border country. Our guide in this exceptional country was Dr. Chad Pritchard from Eastern Washington University in Cheney, WA. Dr. Pritchard was one of the co-chairs of the 2024 Cordilleran Section Conference of the GSA in Spokane, and two of the field trip guides found in the GSA field trip guide #69 from that conference were instrumental in planning this field trip for GSOC. He also co-authored the book Washington Rocks! which was the source of several of the other trip stops.

Attendees at the 90th GSOC Annual Banquet were treated to a fun and informative lecture by one of the country’s prominent petrologic mineralogists, Dr. Barbara Dutrow. She came to talk to GSOC about her passion for using the unique properties of the mineral tourmaline to further geologic research.
