Sand? No. Snow
lit by shopping center lights reflecting off of the clouds.
I am hopefully going to post an evolution of this image within a few days. It took me over an hour and 11 exposures to get what I wanted, I actually shot two I liked. This road leads up to the Olympic Ski Jump which is the white single light in the distance.
I may like this one better, I am not sure yet. Its more painterly. It was photographed before the image above.
