Collaborative Research: The Trail of Time: A Geoscience Exhibition at Grand Canyon National Park

University of New Mexico (UNM) and Arizona State University (ASU) created a paved 3-km walking trail along the south rim of the Grand Canyon in partnership with the National Park Service. The "Trail of Time" is marked as a time line corresponding to Earth history, along with interpretive wayside exhibits. This place-based geoscience exhibition using Grand Canyon as an immersive environment is designed to help visitors gain an understanding of the magnitude of geologic time, as well as key processes and events in the geologic evolution of the region.
