I agree with Anty except one thing... The top of the picture is massively compressed so that there is a visible color (colour for you guys in europe) gradiants.
This was taken with one of the early 2meg digitals - a good few years back - Oh to have been able to use my 40D on the same scene! Rarely there is a short flash of light just as the sun goes down and i spotted this on my way to try and get the sunset over the flooded washes.
