This picture is looking East
across the Willamette River in Portland, Oregon.
The rainbow goes from the Marquam
Bridge on the right to the Hawthorne Bridge on the left.
If you look carefully you will
see a second rainbow just above the very bright rainbow.
The picture below was taken on Saturday, October 17, 2015 looking East during sunset. It was so large it was necessary to take it as a panorama image.
