Field Methods course resumed
The second-year Field Methods course resumed this week after an abrupt stop in April when the province shut down travel out of the county. Students seem very happy to back to learning in person. The course picked up with exercises in the Valley, although the Elderkin Brook exercise had to revert to classroom-only after a 75 mm rainfall on Thursday. Over the weekend the class completed the cross-valley transect and on Monday headed out to Camp Geddie with a few stops on the way to see interesting sedimentary rocks.
Here the class was found pondering on the significance of well-bedded fluvial clastic rocks with interesting channeling (on right) and neptunian dykes (on left).
At Georgeville, students learned about intrusive and faulted contacts in bright sunshine. No coats, bare arms - rare conditions at Georgeville!
Students enjoy exploring the vagaries of metatuff - is that igneous, sedimentary or metamorphic?
Big waves breaking over the dyke prevented close inspection of fault breccia, but maps were made at a safe distance.
At Arisaig, Dr. Snyder expounds on the virtues of flow fold measurements in wildly contorted rhyolitic tuff.
The obligatory class photo by Dr. McMullin, with distancing!
