Abstract

Three exposure ages in the range 80-90 ka, obtained from large dolerite boulders, indicate landslide movement during the last interglacial period; as the deposits show no evidence of movement since first accumulating the deposits must have formed under conditions different from those presently prevailing. The AA. suggest that water-saturation at the contact of the dolerite slope deposits and the sedimentary rocks below, following seasonal snow melt in a period colder than at present, may have initiated instability. The risks associated with land use such as forest harvest on these and similar deposits elsewhere are considered to be low
