Alien Anomalies

ARP2, very nice find my friend, this image has one of  the most blatant image tampering I have seen, but thankfully the blurring is poor and patchy, and misses out covering A,B,C, artifacts (so all is not lost).

My initial impression When I first looked at this image was that the hill had been overlaid onto the bottom of the image (I have still not ruled that out),

I started off at the top of the hill (edge of the blurring) and found a circular object look at arrow "A" which looks mechanical to me, I then moved to the right as there is a light coloured letter C or G shape that attracted my attention (which may be an entrance as it seems to be emitting light onto the next object, look closely next to the letter shape (arrow "B") it looks like a statue laying on the ground, right next to it (arrow "C") is what looks like a landing craft with out stretched landing legs.

However, the most obvious part of this image is shown by Arrows "D", the triangle/pyramid shape is so noticeable even though it highlights the tampering that has taken place, my guess is it could be a large structure that has been blurred and compressed (and maybe dragged down the image at an angle from arrows A+B).
