Polar Bear Den Entrance in Icelandic Snowbank

A deep tunnel cuts into a massive, wind-sculpted snowbank, marking the entrance to a polar bear den. The surrounding ice field stretches toward a glacial stream, its surface textured with frost and scattered debris. Soft, overcast light from low-hanging clouds eliminates harsh shadows, rendering the white landscape in subtle grays and blues. The snow at the den's mouth appears compacted and slightly darker from use, against the pristine powder nearby. Tiny ice crystals glint on the surface of the snow, while the stream below flows with a dark, liquid presence. A faint track leads away from the entrance, fading into the distance where the sky meets the ice. The edge of the snowbank shows a jagged fracture where wind has stripped the surface layer.
