Thank you, I am aware of that finding. I once illustrated it leading inside to the G1 Grand Gallery. Many of my illustrations are for an attempt to garner clarity.
I need to do a better job delineating one over the other. The illustration in this topic is G2.
I searched and found an old file, showing the "chocolate" quarry. When they found the mysterious void, I summarized that possibly there were a connection of Grand Galleries?
A bit of a leap. It's unfinished, thou here it is.
