Entwined in each other’s thick spiral horns, two male Dall sheep pause during a fierce clash. For years, Jérémie had dreamed of photographing pure-white Dall sheep against a snow-clad alpine backdrop. Lying in the snow nearby, he battled with strong winds, heavy snow and bitterly cold temperatures, determined to capture this moment of both ‘purity and power’.

Dall sheep thrive in arctic and subarctic regions of the world. They depend on steep, rugged cliffs and outcrops to provide them with places to escape from predators, while using nearby open grass and meadows to feed. In winter they favour areas with strong winds that remove snow and expose forage.
