Abstract
Field reconnaissance study of a small drainage basin developed on the Chadron Formation (Oligocene) in the Big Badlands, South Dakota, revealed mass movement and piping to be dominant processes in hillslope development. While seasonal creep is undoubtedly a major factor in slope development, evidence of a wide variety of mass movement types is apparent. Piping and associated collapse features occur in mass movement debris as well as in materials in situ on the valley sides. Mass movement features and piped tributary channels show a marked preference for the northeast-facing valley side. As a result, northeast-facing valley-side slopes are complexly faceted in contrast to smooth and convexly rounded southwest-facing side slopes. Field evidence suggests that differences in surface morphology of opposing valley sides arise from aspect-induced differences in moisture budget.
