New high-precision U-Th dates for speleothems from the Assynt caves and their significance for past environmental change

Grampian Speleological Group members are thanked for their continued generous support; without their logistical help this study would not have been possible in this form. We also thank Hamish Couper (then at the University of Oxford) for the U-series analyses, the staff of NatureScot for their friendly logistical support in the Assynt area, and Peter Smart for his permission to re-date the Firehose Cave sample.
