A double rainbow arches across a grey sky over a wide, calm lake

A double rainbow arches across a grey sky over a wide, calm lake. A dense, green forest lines the far bank of the lake. In the foreground, a black metal railing runs horizontally across the bottom of the frame, with a concrete walkway behind it. The scene is likely the Kama River near Chaikovsky, Russia, a city known for its hydroelectric power station and reservoir, which often creates conditions for rainbows. No people are visible in the image.
