From Denny: Popular Science online magazine featured this photo recently. It's from the GeoEye-1 satellite, orbiting at four miles per second, passing over Washington, D.C. during the Cherry Blossom season this April 4th to "admire the view." ;)
The view was shot from the height of 423 miles as the spacecraft moved from north to south along America's eastern seaboard. Along the tidal basin the cherry trees are in full bloom. The huge number of cherry trees were all a gift from Japan to America decades ago.

Someone left this comment on their site:
"Can anyone tell me the time of day that the image was taken?
The Washington Monument makes a fantastic sundial, it's almost a shame the builders didn't insinuate analematic features into the monument-scape of the Mall."
Now there's an interesting idea!
