The excavation was conducted along a slope next to the United Nations Observers headquarters, c. 500 m east of the Upper Aqueduct Park. One square was opened and a quarry with a hewn pit was discovered (Figs. 1, 2). Vertical rock-cut sides (A, C, D) were exposed in the quarry (L100), as well as a rock surface (B) that displayed signs of hewing and removal of a masonry stone (0.60 × 0.65 m). A straightened bedrock surface was exposed south of Rock-cutting D. It seems that the quarry extended westward, beyond the boundaries of the square. A circular rock-hewn pit (L101; 1.25 × 1.40 m at opening of pit, depth c. 0.95 m; Fig. 3) was exposed in the western side of the quarry. The pit became wider toward the bottom (1.65 × 1.90 m), although it was not fully excavated. The pit severed the quarry and it can reasonably be assumed that it postdated it. A meager number of non-diagnostic potsherds were discovered in the excavation.
This area had been surveyed in the past (A. Kloner, 2000, Survey of Jerusalem, the Southern Sector, Sites 24, 77) and building remains that dated to the Iron Age and the Early Roman period were exposed in a nearby excavation (HA-ESI 120).
