The city of St. Louis, Missouri, as seen from across the river. The Gateway Arch dominates the left upper section of the photo, more than twice as high as any of the buildings in the photo. In a horizontal line across the background and behind the Gateway Arch are downtown buildings and some skyscrapers. Lights are just coming on in the buildings even though there is still light in the sky. A line of beach lies between the buildings and the river, which is a dark blue, mirroring the dark blue of the sky.
