In November 2015, the expedition directed by the Czech Institute of Egyptology carried out its fourth excavation campaign at Jebel Sabaloka (West Bank). Efforts were devoted to further exploration of the site of Sphinx (SBK.W-60) in the area of the "Rocky Cities" where a large late prehistoric burial ground, tentatively dated to the 8th millennium cal. BC, had been uncovered in 2012. Altogether 5 trenches, with the square area of 17 m2 in total and with their depths equating to as much as 1 m, were excavated to explore another section of the burial ground and to investigate the settlement stratigraphies in the southern and central parts of the site. Alongside the excavation, selected categories of finds (lithics, ground stone artefacts, animal bones) were analysed and documented. Also, further detailed surface survey and documentation of varied features at the site were performed in order to gather additional data necessary for the preparation of the first detailed report on this remarkable site. Last but not least, special measures were taken to protect the study area from damage by both illegal excavation and gravel quarrying. ; 47 ; 61
