Designator	Floor/Surface
Context rating	Primary
General remarks	Orange surface under collapse. While we changed loci at this color change, we actually dug through this surface thinking that it was to soft and silty to actually be the floor. We later decided that this was the floor and it was actually just incredibly burned.

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.
