Stone-on-stone abrasion pits turning surplus rock into “morale problems”

Illustration: shallow pits carved into bedrock where teams rub large limestone blocks against each other, producing clouds of pale powder. Faces exhausted, posture slumped, piles of powder accumulating like dunes at pit edges. Include simple tools, water jars, and tally marks on a nearby stone to imply the “400 years of grinding” joke.
