Descriptive Attribute	Value(s)
Designator	Wall
Context rating	Primary
General remarks	Locus 170 is a stone wall emerging out of the east baulk of the trench. After removing the east baulk we uncovered a significant extension of the locus running up to the extension of wall Locu s159 in the northern part of the trench.

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.
