The Many Paths of Geoscientists
Address by GSA President Glenn Thackray

Denver and the Rocky Mountain Front region have long supported a concentrated geoscience community, making this is an excellent setting in which to consider the current and future evolution of geoscience career pathways. Rapid changes in federal science focus and resource industries in recent years have caused grave concern for the future of geosciences employment. Yet, geoscience employment has long been both challenging and adaptable, clearly evolving over time as resource needs and societal attention shift. This presentation will examine the many paths that geoscientists follow and the ways in which the field in general and organizations like GSA in particular can support that evolution.

Presenters

Anke Friedrich, GSA President-elect

Bridgette Moore, GSA Executive Director and CEO (Interim)

Sean O’Brien, GSA Foundation Executive Director

Join us as we honor individuals whose contributions have advanced the geosciences. This is more than a ceremony—it’s a celebration of vision, achievement, and community.

Halbouty Distinguished Lecture

Paul Doss

Geologists in the Critical Zone...in a Critical Time

The critical zone, sometimes referred to as "Living Skin of the Earth," is the environment where rock, soil, water, air, and living organisms interact and shape the Earth's surface. Like the human body, perhaps the Critical Zone is Earth's "largest organ." It is in humanity's best interest for all geologists, regardless of specialty, become aware of, become invested in, and communicate about, the importance of abiotic (geological) resources and processes in the critical zone. Too often one can see neglect and ignorance (dismissal) of the geological foundation when ecological conversations arise. Now more than ever, geologists need to champion our science and its importance to the viability of the Critical Zone...something NONE of us can live without.

Kelsey Young

Artemis II to the Moon and Back: The First Step in a New Era of Crewed Scientific Exploration

Monday 12 October

The Artemis II crew were the first people to visit the Moon in over 50 years, captivating the global public as they brought everyone along with them on their journey. The lunar data collected by the crew and by their Orion spacecraft was in service of both addressing fundamental questions about lunar and Solar System science as well as to set future crewed planetary missions up for success as the team developed the processes needed to maximize science in Artemis. This presentation explores the Artemis II mission’s lunar journey, with an emphasis on the lunar science objectives developed by the mission’s Lunar Science Team as well as the structure, processes, and operational concepts developed to prepare the crew, Flight Control Team, and Lunar Science Team to address these objectives. Artemis II was but the first step in returning human explorers to planetary exploration; this presentation will examine the science data collected from Artemis II while looking to the future of Earth to Deep Space human scientific exploration.

Connecting People to Place: A Community Engagement Model for Advancing Geoheritage Stewardship

Tuesday, 13 October

Marilyn Russell and Sabrina Kainz

Marilyn Russell, President, La Veta Trails, Colorado and Sabrina Kainz, Department of Earth and Space Sciences, University of Washington, Seattle

Scientific research has the greatest potential to influence conservation when it is accessible, relevant, and connected to the communities who live within the landscapes it seeks to understand. The Geoheritage of Huerfano and Las Animas Counties Initiative is a partnership between La Veta Trails and the University of Colorado Thermochronology Research and Instrumentation Laboratory (CU TRaIL) that demonstrates how university-community collaboration can translate geoscience research into meaningful public engagement and long-term stewardship.

The initiative combines current geologic research with public trails, interpretive storytelling, regional history, and local culture to help residents and visitors develop a deeper understanding of the landscapes they experience. Community engagement efforts include a dedicated geoheritage web resource, interpretive trail guides that connect geologic processes to on-the-ground trail experiences, public presentations, guided hikes, and youth learning opportunities developed in partnership with the La Veta School. Together, these efforts help people move from experiencing a landscape to understanding its geologic story, strengthening their connection to place and encouraging stewardship.

This presentation introduces a community engagement model that positions geoheritage as a catalyst for education, collaboration, and conservation. By integrating scientific research with place-based learning and local partnerships, the initiative demonstrates how geoscience can foster community investment in protecting significant landscapes while offering a replicable framework for translating research into lasting public impact.
