This is not how quarries usually operate!
If you just glance at the Inca or Pre-Inca quarries as they seem to be, they are really quite strange. Inca 'quarries' look almost 'high tech'. Rocks were sliced and pulled out, as if they were 'soft'. It's as if the whole quarry was soft and they picked and chose what they want. As soon as they sliced the rock, it was done! Then simply fitted into place. Geopolymer, or melted rock, or what?
And how about the tools? How about that first photo? Nubs/knobs already seen in the rock, and PULLED out of the side of the quarry? This is most irregular!
