Description An area of concretion at the bottom of the main gulley, prepared for treatment with explosives. At top right a thin electrical wire will carry an electrical charge from the surface, activating a detonator secured to the looped detonating cord. This will pass detonation along each of the separate runs of cord along which very small charges have been placed. The effect of this treatment was to render the concretion loose enough for excavation without displacing the contexts of items within it (1977).
