Hi, Thanks everyone for checking this out and posting your opinions...
I don't know how big that is... It looks very big as it's not from a narrow image but from a context or wide angle image I believe. It most likely is a structure... and I also noticed the tampering... sigh...
Hi ARP2, I have seen this image before but never looked at it closely before, here is a zoomed in view with markers to what are clearly anomalies (there is also evidence of tampering)....
