Star Trails Wheel Over Frozen River Bend

Curved arcs of white light paint the deep indigo sky above a winding, ice-encrusted river. The frozen water surface reflects the faint celestial glow, creating a shimmering path that mirrors the star trails. Dark silhouettes of conifer trees line the riverbanks, their branches heavy with frost under the cold, dry air. The alpine saddle near Sapporo provides a high vantage point, framing the swirling lights against the pitch-black horizon. A subtle auroral haze adds a soft green tint to the upper atmosphere, against the sharp, cold white of the stars. The ice texture appears rough and cracked, catching the ambient light in jagged highlights. A thin layer of snow dusts the foreground rocks, leading toward the glowing river bend.
