Locus 1 is a brown clay and soil mixture of medium compaction that represents the top layer of the 2022 excavations. The layer is level due to earlier campaigns of excavation lowering the level of the soil north of the OC2/Workshop to the level of the OC2/Workshop floor surface.

The surface of Locus 1 was irregular and contained frequent horizontally growing roots and marks from the plastic tarp. The surface of the layer was compacted and sunbaked due to previous exposure but was a medium compaction once the sunbaked soil was removed. The surface of the layer is at the same elevation as the plaster surface in Loci 2, 4.

Inclusions are composed of many small roots, plaster fragments, tile, and small amounts of pottery. It abuts the northern edge of the OC2/Workshops floor in the eastern extent of the trench (Locus 2). The layer also abuts Locus 6, a smaller stone associated with the construction of the OC2/Workshop. Locus 1 covers Locus 13, a layer of carbon included soil that may be associated with the construction of the floor surface, and also covered the roof collapse of Locus 14.

Not all of Locus 1 was removed during the 2022 season, the narrow eastern most sections of Locus 1 were not excavated. Notable finds from Locus 1 include a slipped pan tile fragment with finger impressions (PC20220005) and a vitrified coarse ware rim fragment (PC20220007).
