During the annual salmon run on the Fishing Branch River in the Yukon, a hierarchy emerges among the grizzlies. Massive males claim the prime fishing spots, while old, wise matriarchs take their stations at the water’s edge, protecting their cubs. This left the younger bears to adapt however they could. Among them was Sophie, a small, lightning-fast female who darted in for salmon scraps and vanished beyond the trees before anyone could chase her off. She made it through the season on speed and nerve, flying up the river like an apparition as her frosted coat caught the winter light.
