In this seminar we will examine numerous issues related to the geology of America prior to the 15th-century. What types of landscapes were encountered by early Native Americans? Did they first arrive here via a Siberia-Alaska land bridge a mere 12,000 years ago, or have people lived in America for longer, say 50,000 years? Perhaps longer? How have American landscapes evolved over the millennia, and how did early Americans adapt? Many of the answers to these questions are contained in the geological record of lake sediments, river terraces, and other geological environments. Readings will include popular and scientific literature and oral histories. 3 hrs. sem./ lab
