The Ribbon of Green Historical Atlas of Edmonton's River Valley is a Beta version of a digital online atlas showcasing the environmental history of Edmonton's most prominent natural feature. This beta version was funded through a $5,000 grant from the Network in Canadian History and Environment (NICHE) and is being hosted by the King's Centre for Visualization in Science (KCVS). The principle investigators for this project were William Van Arragon, Assistant Professor of History at The King's University College and Michael P. Ferber, Assistant Professor of Geography at The King's University College. Research Assistants Katie Wallbaum and Amy VanderHoek wrote a majority of the historical articles included in this atlas.
