Hey, when you don't have steel, you got to make do with the tech of the time, stone blocks

Do you have that image without the pink rectangle?

It has been boarded up for tourists but you can see it in the bottom right corner of this pic

The fact that that specific chamber smells of ammonia today doesn't mean that it smelt of ammonia at the time it was used, so we need to assume that to apply the ammonia theory.

PS: what's so important about ammonia?

It's from bats.  They were well known "pests" of the ancient pyramids (and anyplace else with a dark, cave-like interior.)  Nowadays they try to keep bats out of places like that, but it's a time-consuming effort.

Thanks.

As expected, there's no "stop block" on the original diagram, just a passage.

The (huge) problem here is that none of the seams are leakproof.

The whole structure is riddled with holes because of how badly the blocks fit together.  Even with the mortar.

Why do you think the architects who explored this pyramid randomly added this pit at the bottom of the shaft?

As well as other diagrams?
