In the forefront on either side of the screw are square patches. I have seen these before in photos here. I also saw cables tied and layed in the rows between the squares. What is that?? What are they? How did that preparation get done and by who?

I think these rocks formed by a meteorite, melting and forming a glassy material

Flat rocks? I thought they were ice sheets/chunks.

can any 1 tell me whats there at left side in middle..weird rock??or something else??

I like seeing the gnomen (sundial) schools had them on Earth! Sure r alot blueberries in crkd rego!

Cool! I like how flat the rocks are. Some are cracked like something was dropped on them or hit once with a hammer.
