Moonlit Glacier River Through Black Volcanic Sand

Soft overcast light spills across a wide valley floor in Colorado, where a glacier river winds through dark volcanic sand. The water flows with a milky gray hue, contrasting sharply against the jet-black grains of the riverbed. Dramatic clouds stack high in the sky, their undersides glowing faintly with the first light of sunrise. The river curves sinuously, creating a pale ribbon that cuts through the rough, uneven terrain. In the distance, faint outlines of mountains rise, their peaks softened by the diffuse atmosphere. The black sand stretches endlessly, its texture rough and granular, catching the subtle light. A small ripple breaks the surface, reflecting the pale sky above, marking the edge where water meets stone.
