Combined with	Loci 2-16.
Description	Thirteen courses in height in the north (eight courses above the Locus 6 Platform landing and four courses above the Locus 7 steps, after which there is collapse to one course above the Locus 8 Platform landing, the west wall is constructed with well dressed sandstone ashlars, many of which have slumped out of position. Like Locus 2, there originally might have been a doorway here that underwent modifications. It was intended to serve as a major stairway wall, and in sporadic patches of its building it is sturdy. On its east face it is but one row in thickness, but its interior shows that it is constructed similarly to other Nabataean walls and is casemate in construction with two well dressed faces with rubble fill in between. It appears that this wall collapsed to the east and onto the stairwell. It is also apparent that the lower courses of this wall east face show there were ancient repairs. Stones are inserted to support the upper courses of ashlars extending from the lowest course to three courses above and snecking stones have been jammed between the lowest to the fifth row above of exposed ashlars. Obviously Locus 2 was put in place to mask these defects. In appearance this wall has had its north south orientation compromised in antiquity and it leans to the west, pulling away from the staircase. But it is also here that the Nabataean builders may have had a problem with orientation and the blending of the Great Temple precinct with that of the West Baths. The axis of the two sectors is appreciably different, and as the stairway served both areas, its west wall might have been intentionally compromised and oriented more to the west to serve both precincts. This suggests that the city plan may have been modified with the construction of the West Baths. This wall is assigned to Stage 1 of the Staircase because the stairs and platforms are built up to it, and it serves as the frame for the West Entry Stairs.
