Look to the left corner of the tripod in this image. It appears as though there is a block being lifted by a woman in a hat. Also, her face is looking away from the camera and focusing on this unusual object that appears to be a rod with two items winding up it. Perhaps I am completely off base, but I believe that the image of Ed in the front with his quarry is a false flag for the real information the image is providing that is located behind him. The woman appears to be either lifting the huge block behind him or on the block. It is hard to tell.
Could you circle the object in question?
It seems like he has a stabilizing pole from his tripod pointing directly at it.
This is an enlarged image of what I am talking about.
Like I said, it could be nothing, but it did seem pretty interesting.
