The preglacial (paléic) landscape configuration in the Sognefjord drainage basin of western Norway is reconstructed, and the total Quaternary erosion is quantitatively determined to 7610 km 3 by subtracting the present topography from the reconstructed preglacial surface. With an average erosion of 610 m during the suggested time span of 600,000 yr when Scandinavian ice sheets reached the continental shelf off western Norway, mean Quaternary erosion rates are calculated to ca. 1.02 mm/yr. Using the average relief of 2000 m along the fjord, however, the rate of glacial erosion was 3.3 mm/yr. Taking into account the selective nature of glacial erosion by ice streams along the fjord, an estimate of 2 ± 0.5 mm/yr is likely. Limited to the east by the main watershed, a rough estimate of the total Quaternary glacial erosion in the fjord region of western Norway is calculated to about 35,000 km 3 of rock. With a soft-sediment porosity of 30-50%, this corresponds to about 45,500-52,500 km 3 of continental shelf/deep-sea sediments.
