General remarks	This locus is located in the corner of the west baulk and L130. Above it, in the baulk, a thick layer of ashy debris is visible. Possibly, this locus is the bottom of this burnt layer, because after removing its contents, an orange, hard clay surface appears underneath it.

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.
