The Calhoun CZO held its third annual Summer Science Days meeting. In the photo, Calhoun researchers discuss a 18th-19th century pine root buried by historic legacy sediment. Legacy sediment are sedimentary deposits resulting from human-accelerated soil erosion. Nearly all valleys with floodplains in regions occupied by humans are affected by deposits of legacy sediments.
