This video features discussion of the kinds of tools used to excavate at the Cooper's Ferry site. Also, the effect of animal burrowing on archeological deposits and how they are handled during the excavation process is discussed. The infilled tunnels left behind by burrowing animals are called krotovina (sounds like crow-toe-vee-na).
Dr. Loren Davis, Associate Professor,
at Oregon State University and David Sisson, Archeologist, at the BLM Cottonwood Field Office
http://www.blm.gov/id/st/en/Districts-Idaho/CDA/cottonwood.html are working together to recover information about past life ways at the Cooper's Ferry archeological site. Students from the Oregon State University Cooper's Ferry Archaeological Field School
uncover artifacts that help us understand what life was like for people who occupied the lower Salmon River Canyon thousands of years ago.
