Lighthouse Beam Sweeps Amazon Valley at Night

A razor-thin ribbon of white light cuts horizontally across the dark valley floor, momentarily illuminating the jagged edges of rocky outcrops. The beam originates from an unseen source on the right, sweeping leftward over a wide expanse of Amazonian terrain. Low-hanging clouds drape the upper valley in a heavy gray blanket, their undersides catching the glow of the passing light. Dark silhouettes of steep rock formations stand against the luminous haze, their rough textures defined only where the beam strikes them. The surrounding landscape remains in deep shadow, showing the stark contrast between the artificial illumination and the natural darkness of the cool night. A faint reflection of the light glimmers on a smooth, wet stone in the immediate foreground.
