Designator	Feature
Context rating	Secondary
General remarks	Rock group against center-W baulk. Looks to be mixed rock and mudbrick collapse contemporary with the other Ubaid contexts and probably from the same collapse. The reason for the concentration of rocks, however, remains unclear.

Has note	Contexts excavated in trenches were recorded using the "locus system." A locus is any discrete three-dimensional entity excavated in a trench. The key to the locus system is the recognition that a locus is any one thing. Differences in soil composition or texture are therefore as important as, for example, the difference between a pit and a wall. If two entities were distinct, they were considered separate loci and were therefore assigned separate locus numbers. It should also be noted that every context excavated in a trench was given a locus number and thus the trench itself is made up completely of excavated loci.
