Opis

This volume had its origins in an international symposium organised by the Cold Regions Research Centre, and held at Wilfrid Laurier University in November, 1999. The chapters are modified from a selection of the papers at the meeting, and reflect reviews and revisions in light of discussions then. The original idea for the meeting was to address certain questions that the organisers were encountering in their own work, and that we felt had received limited attention in the recent literature. The two broad issues we wanted to address were: the complex associations of actual landforms and processes in cold regions, and how the almost universal legacies of past, different cold environments of the late Quaternary affect these landscapes in the present. The former involves the problem of identifying landform and sediment complexes, and the interrelations of relevant processes. We sought to identify this in terms oflandform and sediment assemblages appropriate to regional and field-oriented concerns.
