Description	Locus 25 represents the bedding for a flight of stairs. It seems logical that these stairs originated in the Lower Temenos, but excavation has not extended far enough north to determine this with certainty. The steps would have been covered with risers that have been robbed out. There was a great deal of plaster that came up in the loci that covered the bedding, and Step 6 still has plaster on its western side. Along the east side extends Locus 20, ashlar wall, which is Nabataean. Because the steps follow the wall so perfectly, the steps are probably also Nabataean. They are 2.11 m in east-west width, and they are made-up of flat, sandstone ashlars between 0.30-0.40 m in length.
