Deposit appeared to comprise burnt adobe before excavation began. During excavation it became apparent that the soil matrix comprised concotta, essentially baked soil. Parts of it were intensely red. A tufo slab with uneven edges was situated in the center of the SU. It had a good number of hair line fractures which may have been caused by intense heat. A black halo around the tufo slab suggests it was burnt in situ. After the removal of the slab, another in a similar position was found beneath it in SU 2296. SU 2284 was found to sit within a shallow, cut and together with 2296 appears to have functioned as insulation to a fireplace, represented by its upper surface.
