The Earth and Environmental Science Department and the programs in Art teamed up to host a special cross-disciplinary presentation entitled Boundary|Time|Surface: Art and Geology Meet in Gros Morne National Park, Newfoundland, Canada by artist Sydney Lancaster and geoscientist John Waldron. Normally resident in Edmonton, John is a Harrison McCain visiting professor at Acadia in the fall term. Sydney and John coordinated the installation of an ephemeral sculptural work created to interrogate the brevity of human experience relative to the enormity of time, and the fragile and arbitrary nature of human-defined boundaries. In the presentation, John outlined the significance of the system stratotypes, and Sydney presented an overview of the construction of a fence of driftwood poles erected to mark the Cambrian-Ordovician boundary at Green Point, Newfoundland. A publication arising from the project can be purchased from the Atlantic Geoscience Society.
