This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $414,744 to Colorado State University from September 2022 through August 2025 to investigate past, present, and future glaciated alpine landscapes using integrated data and modeling. The award supports developing detailed modern and paleo glaciological datasets from the Teton Range in Wyoming and integrating them into a state-of-the-art glacier model (PyG2D) to simulate past and ongoing glacier retreat. This model includes novel representations of topographically-mediated mass balance processes important as glaciers shrink. The open-source PyG2D model can then be applied globally to quantify climate change impacts on mountain ecosystems, hydrology, and landscapes. The project aims to advance understanding of deglaciation processes in alpine settings by placing modern and future Teton glacier change in the context of fluctuations since the last ice age. Results will inform heavily glaciated region evolution and serve as tangible examples of climate change cryosphere impacts for resource managers and policymakers.
