Abstract
Glaciation may be considered a perturbation of normal fluvial conditions. Drift is unstable in a proglacial or postglacial fluvial environment, resulting in heightened sediment movement that continues as long as drift material remains easily accessible for fluvial erosion and transportation. Sediment yield bears no relation to concurrent primary productions of weathered debris. Examples of such paraglacial denudation and sedimentation from two contrasting areas are discussed. Postglacial valley alluvial deposits are widespread in central Baffin Island where rapid sedimentation continues today; estimated denudation rates are an order of magnitude higher than in comparable nonglacial areas. In south-central British Columbia, rapid sedimentation during Pleistocene contrasts sharply with present-day conditions.
