Teaching Mineralogy, Petrology and Geochemistry Post-Workshop Field Trip

An Excursion to the Classic Bedrock Localities of Northern Minnesota With a Focus on Teaching and Learning in the Field

Field Trip Leaders: Karl Wirth, John Goodge, Dexter Perkins

The goal of this three-day field trip is to explore the opportunities and challenges of teaching geology in the field. The trip will use several classic bedrock localities within the scenic Lake Superior region of the Mesoproterozoic Midcontinent Rift to foster discussions about pedagogies that can be used for teaching students in the field. Extended visits to a world-class turbidite sequence, layered igneous intrusions, and well-preserved volcanic and sedimentary sequences will provide participants opportunities to experience learning geology as student, and to explore new ways to improve student learning in the field.

Dates: August 11-13 (Leaving U MN area Thurs AM, returning Saturday night)

Cost: The cost of the field trip is $325. This includes transportation, Thursday and Friday night lodging (double occupancy), lunches and snacks on the road, and guidebook. Breakfast and dinner will be on your own at local restaurants. Note: we will be returning to the MSP area on Saturday night, and you will also need to plan for lodging for this night. We will attempt to make group arrangements expecting Sunday departures. The cost of Saturday night lodging is not included in the field trip fee.

Registration: Space is limited to 30 participants, and was accepted on a first-come first served basis. Registration ended May 15.
