At the alumni reception – a reunion.

Elliot Miller (Wooster) presenting his IS work on geochemical analyses of palagonite and potential applications to Martian exploration.

Mary Palmieri (Wooster) investigates the linkages of tree rings and cloudiness in Northeast US.

Lynnsey Delio (Wooster) is investigating the linkages between coastal Alaskan tree-ring records and the monthly Lake Huron and Michigan levels.

Lauren Segura (Wooster) presents her work using crystal size distributions to help determine the origin of extrusive rocks in Iceland.

Ihaja Metz (Wooster) is working on using the XRF at Wooster in determining water chemistry in natural groundwaters.

In addition to the presentations by Wooster students and faculty – four Keck Geology Consortium students who worked at Wooster in the summer of 2025 presented results. Here Dexter Pakula (Carlton College) presents his study linking modes of climate variability in the Indian Ocean to climate variability in Alaska.

Lev Sugerman-Brozan (Colorado College) explains the results of his work comparing tree-ring reconstructions Gulf of Alaska temperature variability and model simulations focusing on intervals of strong volcanic forcing.

Landon Vaughan (Trinity University) explored the record of volcanic cooling of the late 1690s volcanic event(s) their signature in the rings of yellow cedar trees and linkages with Tlingit oral histories.

Izzy Held worked on the feasibility of using costal tree-ring records from the Gulf of Alaska to reconstruct Mendenhall River flow from Juneau Alaska.

We are grateful to the many alumni for their support and their contributions that helped to fund the travel and stay in San Antonio.
