Glacial History of Jackson Hole and the Tetons

Explore the glacial history of Jackson Hole, the Teton Range, and the greater Yellowstone region in this comprehensive geological presentation by Dr. Joe Licciardi. Learn how the geomorphic evolution of the Teton Range has been shaped by successive Pleistocene glaciations combined with late Cenozoic displacement along the range-bounding Teton normal fault. Discover how an extensive network of mountain-valley glaciers created well-preserved moraine sequences and ice-scoured bedrock that document a complex history of glacial and tectonic activity. Examine the extensive outwash deposits and terraces that characterize Jackson Hole, which originated primarily from glacial episodes associated with the Yellowstone ice cap to the north. Investigate ongoing research focused on determining the precise timing of deglaciation on the Yellowstone Plateau during the late Pleistocene, including the unloading of the 1 km-thick ice cap and its far-reaching implications. Understand how this deglaciation timing affects multiple scientific disciplines, including the initiation of Yellowstone's hydrothermal systems and features, potential triggering of hydrothermal explosions, impacts on volcanic-magmatic processes, influences on tectonic activity, paleoclimatic controls on glacial retreat, and the development of postglacial ecosystems and environmental conditions.
