Palliser Rockslide cosmogenic 36Cl exposure ages (raw data) and erosion effect on the cosmogenic

This paper presents the results of a combined study, using cosmogenic 36Cl exposure dating and terrestrial digital photogrammetry, of the Palliser Rockslide located in the southeastern Canadian Rocky Mountains. This site is particularly well-suited to demonstrate how this multi-disciplinary approach can be used to differentiate distinct rocksliding events, estimate their volume, and establish their chronology and recurrence interval. Observations suggest that rocksliding has been ongoing since the late Pleistocene deglaciation. Two major rockslide events have been dated at 10.0 ± 1.2 kyr and 7.7 ± 0.8 kyr before present, with failure volumes of 40 Mm3 and 8 Mm3, respectively. The results have important implications concerning our understanding of the temporal distribution of paraglacial rockslides and rock avalanches; they provide a better understanding of the volumes and failure mechanisms of recurrent failure events; and they represent the first absolute ages of a prehistoric high magnitude event in the Canadian Rocky Mountains.

The 1996 BFA Graduating Class Department of Visual arts

The work presented in this catalogue represent ten years of study, thought, practice and application. While each member of the fourth-year visual arts class has selected just one image and chosen only a few words for inclusion in this record of our graduates and the program, it is important that we understand the dimensions of experience and learning symbolized on these pages. The women and men represented here have all passed through a rigorous course of academic study,personal and professional development, and technical training. They have engaged issues and concepts from both theoretical and practical perspectives, and have been challenged to stretch their thinking about community, society and the world in terms past, present and future. These Students have translated ideas and insights into works of art in a variety of media.
