Even though it has been three years since Brian (Barney) Reeves died in August of 2023, it is a testament to his profound impact on the field of archaeology and more importantly on his former students, colleagues and friends that we gather in Canmore to remember and celebrate his impressive legacy. The papers to be presented at this session reflect Barney’s influences and foundational ideas in archaeology - his major contributions to Plains/Mountain culture history and classification through his pioneering recording programs in Waterton National Park and the Crowsnest Pass, his deep interest in northern plains ethnography, ethnobotany, communal bison hunting (Head-Smashed-In), archaeoastronomy and ceremonial landscapes, all of which was enhanced by his decades-long and close friendship with a number of Piikani elders. Also to be considered was his amazingly wide first-hand familiarity with the archaeological literature and artifact collections inside and outside of the plains and his impressive ability to synthesize vast quantities of information into comprehensive models of culture history. He brought an insatiable curiousity and dedication to the research he took on and profoundly influenced many of us throughout our careers.  The papers to be given in this session honour his memory and personality, his ongoing academic legacy and highlight the large number and variety of contributions he made to archaeology.
