This first Neolithic, however, can also be seen as the last gasp of an earlier way of life that OPEN ACCESS remained fundamentally Epipaleolithic in character.

Site background Nachcharini Cave (Fig 2) is located at an elevation of ca. 2100 masl in the central ‘Ard al- Kichek plateau of the Anti-Lebanon Mountains (al-Jebel ash-Sharqi) in eastern Lebanon, near Fig 2.

Unlike the lowland villages that have been the focus of most research on this period, Nachcharini is thus at the highest elevation of any known early Neolithic site in the Levant, making it a truly montane site. Its environs are characterized by rolling land broken by karstic sinkholes that create small, steep-walled canyons and valleys. These landforms provide a good potential habitat for wild sheep, and there are steeper peaks and slopes nearby that would provide habitat for wild goat and mountain gazelle. The presence of deer in the Nachcharini faunal assemblage suggests proximity to wooded areas. During win- ter, the plateau receives significant snowfall, and snow often persists there until May or June. The plateau may well have sustained vegetation suitable for grazing and browsing herbivores into the late summer, when available resources may have diminished in the adjacent lowlands. Jacque BesancËon discovered Nachcharini Cave about 1970, and Bruce Schroeder subse- quently excavated at the site in 1972 and 1974. Significant disturbances at the site substantially reduced the area available for excavation. The 1972 season produced a stratigraphic profile in an exposure of approximately 0.5 m2 and pointed to the richness of the PPNA component (Fig 3). The excavation of 1974 expanded the initial exposure of the PPNA to a total of Fig 3. Stratigraphic profile of Schroeder's excavations at Nachcharini Cave. L. Wadsworth and S.

Excavation was in 1 m2 units, subdivided into 9 subsquares, with baulks left that reduced the excavation area (Fig 2C). Schroeder's excavation involved attention to full recovery of all materials and is an early example of the use of the décapage method, with expo- sure and photography of in situ surfaces of artifacts and fauna preceding any removals. Schroe- der identified a sequence of five levels (Fig 3). Here we focus on Layer 4d at the bottom of PPNA Layer 4, in which Schroeder exposed a dense concentration of remains. Layer 4d was reached in three squares (D9, D10, and E9) although part of the area was disturbed by intrusive pits. As Fig 4 shows, Layer 4d was excavated as two surfaces, the upper 4d1 and the Fig 4.
