Quaternary tectonics along the flanks of the Yellowstone hotspot

Quaternary tectonics along the flanks of the Yellowstone hotspot from terraces along the Hoback and Snake River

The Yellowstone region is a very dynamic area on the North American continent and has seen striking tectonic changes that are linked to the passage of the North American Plate across a hot mantle plume. With collaborators at Utah State University, we study rivers along the flanks of the Yellowstone national park. These rivers incise into the rocks that get lifted in response to the hot mantle underneath them. Studying the terraces and the stream profiles in the region can yield insights into the rates and the pattern of the surface response to the hot mantle. This project is a preliminary study with the long-term vision to link mantle dynamics to surface processes, and to better understand the time and spatial scales at which tectonics and climatic forcings influence landscape evolution.
