Yes...it’s difficult to tell if they are all the same shape or not, and what the water situation is there—would both food and water be required, or just food/forage?
I would think that water storage would be different. Either grouped around streams that sometimes ran dry or why not dig wells.
What is most amazing about all of the ancient stone structures is how did they do it. What tools were used. Did they know to make a small hole and then fill with boiling water and form cracks. or build a fire right in the rock.
