GSA report: the James Shea Award

I’m at the GSA Annual Meeting in Indianapolis this week, and I got an award today: the James Shea Award from the National Association of Geoscience Teachers. I was introduced at the awards luncheon today by my co-nominator Kaatje Kraft, who had many nice things to say. I followed her comments with this little speech: Thank you, Kaatje, and also to Joshua Villalobos for nominating me. I’m getting this award …

Friday fold: Squaw Creek Schist, Idaho

The edge of ancestral North America can be found in the canyon of the Salmon River in western Idaho. Folds exposed the Squaw Creek Schist near Riggins record the stresses of adding terranes on during North America’s westward movement since the breakup of Pangaea. The Friday fold crinkled up during the accretion of a terrane to the growing North American continent.

Friday fold: Torqued talc from the 2016 Biggs awardee

Callan’s colleague Joshua Villalobos won the 2016 Biggs Award. He also makes GigaPans of folds, like these talc-bearing rocks of the Allamoore Formation.

Friday fold: Mesoscopic structures in the Lightning Creek Schist

There are some structural goodies here at the confluence of the Rapid River and the Salmon River in west-central Idaho. I visited these outcrops three weeks ago on a field trip after the Rocky Mountain section meeting of GSA. The rocks are the Lightning Creek Schist, a schist that’s part of the Wallowa Terrane, an accreted chunk of crust that docked with western North America during the Mesozoic. Here is …

Friday fold: core

At the Rocky Mountain Section meeting of the Geological Society of America this week, there were several displays of interesting cores. I’m not sure where this one came from, but it had a fold in it, and since no one else had volunteered a Friday fold for this week, I took a photo: It’s standard core diameter; I’d guess that’s about 2 inches. Given that I’m headed out on an …

Corridor H virtual field experience

My Historical Geology class was in for a new experience for the semester’s capstone field trip. Before we headed out into the field (to the exceptional roadcuts along Corridor H in Grant and Hardy Counties, West Virginia), we had them examine all the outcrops virtually, in the comfort of the classroom, using digital imagery. I say “we” because this initiative was a collaboration with my colleague Alan Pitts, who developed …

Seven new GigaPans from Axel Heiberg Island, Nunavut

One of the cool things about my plan for the GEODE grant from NSF is to put GigaPan imaging systems in the hands of people who will take them to cool places. I purchased five loaner GigaPan rigs, and they have gone out in the field with various people, but I think that the images I will show you today are the coolest we’ve yet produced. All seven of them …

Awesome field trips at GSA Baltimore meeting

Hi everyone, As the deadline for early registration for the annual meeting of the Geological Society of America nears, I’d like to call your attention to a suite of awesome field trips exploring mid-Atlantic region geology. If you’re traveling to the east coast for the first time for GSA, or if you’ve never ventured beyond the Smithsonian and NSF conference rooms, then you should consider one of these trips as …

GSA and the Biggs Award

The recently-concluded Geological Society of America meeting in Vancouver, British Columbia, was one of my best meetings ever. I gave two talks and a digital poster, supervised three student digital posters and one student group regular poster, attended and contributed to meetings on a variety of subjects, met new colleagues, reunited with old friends, and even attended some stimulating science talks. Plans were hatched, ideas refined, projects discussed. Tuesday was …

GSA – Halfway through the annual meeting

These annual meetings of the Geological Society of America seem to fly by faster and faster. I’ve found that, through the years and as my career has developed, that I have less and less time for attending talks or contemplating research presented on posters. Instead, I spend my time sharing my own work, supporting students, networking and catching up with colleagues, and attending meetings for various groups and projects. Less …
