A photograph of the Santa Ana riverbed at sunset, looking towards a pedestrian bridge. The basin has almost no water in it, so you can see the concrete bottom and the pylons that hold up the bridge. It looks like there is a small stream of water in the middle, but that might just be darker-colored concrete. The sky is blue at the top left corner and fades to yellow at the bottom right corner, with bright pink clouds in the middle with fingers reaching out across the sky. There is a row of trees or large bushes that are black against the bright, fading sky, which make a line between the concrete and the sky.
