Abstract
A dated landscape history of the Allt nan Uamh valley in the Assynt ar ea is constructed, spanning the last 300 ka, using geomorphological an alysis, U-series speleothem dating, and existing cave surveys. The mea n rate of valley deepening is estimated to lie between 47 and 68 m per glacial/interglacial cycle of 100 ka. This, combined with an estimate d duration of glaciation, implies glacial erosion rates of about 2 mm a(-1), in agreement with modern process measurements. (C) 1997 by John Wiley & Sons, Ltd.
