Glacier 2018-19 Project Spring Update

Team members examining core in the LacCore facility

Eight Gateway students spent two weeks in the wilds of Glacier National Park in July 2018. They saw bears and moose almost every day, including waking up one morning to Park Rangers yelling “Bear in the camp”! The team collected lake sediment cores from two lakes (Fishercap and Swiftcurrent). In Swiftcurrent Lake the cores included volcanic ash units from the Mt. Mazama eruption (~7,600 years ago), and older eruptions from Glacier Peak and Mt. St. Helens. Students and project directors presented two posters at the Fall GSA meeting, and Kelly MacGregor and Amy Myrbo presented their model of Gateway projects at the Fall AGU meeting.

Team Catalina at their posters at the Fall AGU meeting in Washington DC.

Students started the project in Oberlin, learning about metamorphic geology, and collecting major element data using SEM/EDS. The then moved to the West Coast, visiting field sites on Catalina and collecting additional samples based on observations made in Oberlin. The final phase of the project took place at Pomona College where students collected trace element data on garnets, synthesized data, wrote abstracts, drafted figures, and made posters. Finally, most of the students came together to present on their posters at AGU. While at the meeting, the students had lunch with two prominent researchers of their field area and their graduate students and were able to discuss their results in a more relaxed environment.

Nine students collaborated on three posters. There were able to use rock textures observed by SEM, major and trace element analyses to show similar metamorphic histories preserved in garnet-hornblende of different textures and with and without plagioclase. A second team showed evidence of polymetamorphism in a garnet-blueschist block with late lawsonite. The their team was able to show different but overlapping metamorphic histories from garnets in a tectonic block and a texturally-late metasomatic rind.

Keck Alaska 2018 research team admiring bears in Anchorage.

The Keck Alaska team is off to Portland, Oregon to present their work at the GSA Cordilleran section meeting May 15-17. It turns out this was the perfect meeting to attend thanks to a big focus on Alaska and the Pacific Northwest this year; therefore, every team member is presenting as a first author for a total of eight papers! A complete list of the talks and posters we are presenting can be found here.
