The exhibit shows how the Greater Yellowstone Ecosystem is a landscape of “Invisible Boundaries” that is permeable to wildlife. In fact, animals rely on being able to migrate freely across state, Yellowstone National Park, National Forest, and private property boundaries to survive and keep this ecosystem intact. WMI research associate Dr. Arthur Middleton and WMI Photography Fellow Joe Riis independently produced this exhibit with artist James Prosek and filmmaker Jenny Nichols. WMI co-sponsored the exhibit and contributed to the maps.
