(Simon Fraser University) A study led by SFU archaeology professor Dana Lepofsky and Hakai Institute researcher Nicole Smith reveals that clam gardens, ancient Indigenous food security systems located along B.C.'s coast, date back at least 3,500 years -- almost 2,000 years older than previously thought. These human-built beach terraces continue to create habitat for clams and other sea creatures to flourish in the area.
