What Rivers Tell Of Earth's History

Rivers tell explain much about the Earth's development, both from the past and in the present. Liz Hajek, a geo-scientist at Penn State University, presents remarkable photography and information on now dynamic landscapes can be formed and the implications. Using rivers as "time machines", Hajek shows that by jumping their banks and other geomorphological events can be studied using hydrologic records to investigate similar landforms throughout history. Her research asks questions as to how we should respect and learn to coexist on our constantly evolving planet.
