Dall Sheep, AlaskaDall sheep are native to the rugged peaks of Alaska and northwestern Canada, easily recognized by their bright white coats and impressive curled horns (although not this adolescent). Built for steep terrain, they can scale rocky cliffs with incredible agility, using specialized hooves that grip narrow ledges with ease. I spotted this one along the Seward Highway outside of Anchorage, Alaska. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/320th of a second.
