I suppose it should. I mean, it sort of looks like a rectangular QR code. but the keys down at the bottom remind me more of an electrical wiring or a resistor; I haven't made the mental leap to link them yet.
I'm not even certain what we're qualifying as "dashes" and "dots" here. Vertical vs horizontal makes sense, I guess, but what about the degree to which the horizontal blocks are filled in?
Still puzzling through this one. I have the three keys, but no answer. That said, I see that the map outlines on the edges of the page match those of the full map of the excavation site in the notes section
