Hand piled rocks walls, just over a kilometer long, around 9 meters tall, and 15m wide, all pulled from the creek bed and stacked neatly into a buttress that the crew would live on. Pic related, the hand piles go all the way up the left slope of the creek, almost 100m above the creek in places, the layer of rocks is in places a meter thick. All that material was washed / worked by hand, these are older than similar walls done by crews of men with hydraulic cannons. The work must have been unimaginable.
