Three friends set off on a 400km bike packing and packraft expedition through the heart of the sacred headwaters in northwestern British Columbia, birthplace of three critical salmon rivers, and home to the Tahltan people. In the wake of the devastating Mount Polley Mine disaster, the team’s goal is to understand what is at stake as a wave of new mines are developed across this remote corner of the province. Their journey offers an exciting and sobering window into this wild landscape as they pedal through vast boreal forest, paddle frigid whitewater, battle monster trout, outrun a grizzly, learn about the Tahltan’s fight to protect their homeland, and glimpse inside a massive open pit mine.
