General remarks	Locus 168 is a fill locus encomposing the southern two thirds of the trench, and represents the area south of wall Locus 159. We uncovered an emerging surface Locus (171) below this locus that could represent an associated outdoor work surface.

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.
