Yes, this actually IS a sunset, not a moon-rise! The sun had set a few minutes before I took this shot and the light levels had dropped VERY quickly. Odd for my lattitude, but it sure made for a nice image!
The Sun was setting, the sky was on fire, the clouds above me were raining but the rain wasn't hitting the ground... what a Sunset!
Those high clouds seemed to be an echo of Light coming from just off of the Sunset! This is in the valley just east of Tukwilla, Washington.
