Lighthouse Beam Sweeping Rocky Pampas Coast

A sharp beam of white light cuts through the deep night, sweeping across a wide valley floor in the Pampas. The illumination reveals jagged rocks and low grasses in stark contrast to the surrounding darkness. Silhouetted structures stand against the glowing arc, their forms defined only by the edges where light meets shadow. The sky above is perfectly clear, devoid of clouds, allowing the beam to travel unobstructed. Textures of rough stone and dry vegetation become visible as the light passes, then vanish again into the night. at the edge is the thin, bright line of the beam grazing the tip of a distant rock formation.
