Horemheb tomb (KV57), Luxor, EgyptEvidence of flash flood related erosion in the Esna Shale and vertical fissures in Unit 1 of the Thebes Limestone, delineation of the abandoned Excavations and its causeway. The subvertical wall-cuts were dug in the upper part of the Esna Shale Formation and at the base of the Thebes Limestone Formation. White arrows point to erosional gullies in the lower part of unit 1 of the Thebes Formation, in the Hanadi Member (Esna Shale Formation) and in the debris that cover the Esna Formation. Note that the gullies at the base of the Thebes Limestone and just below are commonly hollowed out, in particular on top and below the prominent base of Unit 1. These are probable evidence of flash floods. fallen blocks; unstable columnar block and open vertical fissures; screes. screes resulting from archeological excavationsBack to article page
