Schematic drawing of the current profiles of the Upper Cutting (see SI Appendix, Figs. 5 and 6). (A) The éboulis above northwestern corner of the excavated cutting. (B) Levels 2m-2o breccia containing human bones. (C) Projection of the éboulis scree slope, which is less perceptible in this profile than it had been in now removed sections parallel to it in the foreground. (D) Uppermost limit (levels ≈2h-2i) of lens of burnt sediment mainly in the northeastern area of the cutting. (E) Lower limit of burnt ashy sediment (levels 2m-2o) in the northern and eastern area of the cutting.
