Over the last four years, members of the Iyarhe (Stoney) Nakoda Nation and the Mountain Legacy Project have collaborated on repurposing a colonial photographic archive to support Indigenous resurgence. Through archival research, a systematic collection of high-resolution historical (1861 to 1958) images has been used to reinforce Stoney ties to the lands around present-day Banff National Park, Alberta, Canada. Combined with repeat photographs showing the landscape as it is today, the images provide a powerful testimony of change and urge us to look to a future of Indigenous-led land management. In this presentation we will report on several applications for historical and repeat photographs including: youth and Elder engagement; place naming; and landscape change analysis using custom software tools developed at the University of Victoria.
