The directionality of mudbricks, potsherds, and grains. (a) 400-kg quern, at left, used for grinding grain, is tipped over with top towards NE. Image view spans ~ 2.5 m. Area #1 shows broken pottery and meltglass piled against quern from SW to NE (arrow). Area #2 contains charcoal, charred grains, ash, and mudbrick fragments, but no potsherds, suggesting that the quern shielded the floor to the NE. The area at the top labeled ‘blow-over’ is evidence that strong winds sealed the deposit with windblown laminated material that includes pulverized mudbrick, charcoal, ash, and fragments of white plaster. The draping of the blow-over indicates debris traveled from SW to NE. The scale stick is in 10-cm intervals. (b) Directional potsherds. Blue, red, and green asterisks (*) represent color-coded potsherds from three different pots. Arrows mark the motion of potsherds from SW to NE, spanning ~ 1 m. Area #1 represents the inverted bottom of the pot with its smaller fragments strewn to the left. Some pots contained charred grains also strewn in a SW-to-NE direction. Radiocarbon dates on charred grains confirm an age of ~ 1650 BCE (3600 cal BP).
