The iconic muskoxen, standing steadfast against the relentless winds of Bathurst Island in Canada's High Arctic, are living remnants of a prehistoric age. Their ancestors wandered this stark landscape for tens of thousands of years, crossing the polar desert in search of the sedges, willows, flowers, lichens, and grasses that sustain life on the Arctic tundra. Shielded by qiviut—one of the warmest and most prized natural fibers on Earth—these remarkable animals endure and thrive in one of the planet's most unforgiving environments.
