For the next challenge I give you an area I have had in mind for some time:
blog. Enjoy your search!
It's been a few days, so here is a hint: The right side image was taken on March 12, the left side on November 2.
Maybe a larger view will be helpful.
Still no guesses, so I will share a close-up. This is from the top left corner of the first view, or the top right of the second view.
