Abstract: | Historical forest clearance and agriculture have had profound effects on the landscape of the southeastern United States. This study examines a site called Monument Hill located in the eastern foothills of the Blue Ridge Mountains in central Virginia in order to better understand the long-term effects of historical agriculture on soil and streams. This site, deeply gullied and drained by an incised first-order stream, was first settled in the mid-eighteenth century and became part of a large nineteenth-century plantation. A thick sediment fan at the base of the hill buried and preserved a historical soil surface, archaeological artifacts, and woody debris datable by dendrochronology. The geomorphology of the site, along with limited historical data and tree ages from the mature second-growth forest cover, has enabled reconstruction of the sequence of land-use changes and measurement of geomorphic response over two and a half centuries. |
