Taken from the summit of Steptoe Butte overlooking the rolling hills of The Palouse in eastern Washington state. I was surprised that so many of the photographers who had gathered on the butte for sunset had left just after the Sun had gone down. About 10 minutes after, the sky lit up and the fields that had a strong green color earlier had turned a more blueish green. The remaining glow in the sky delivered a beautiful subtle brightening to the hilltops that set them apart from the shadowy dips in between. It made the entire vista appear like it was waves on the ocean.
