Top, photograph of a pit wall in trench 3. From the floor of the pit to the top of the bench is approximately 2.5 meters. Boulders and cobbles comprising the conglomerate are evident in the pit wall. Small pink paint spots mark metal detector strikes in bedrock. Bottom, photograph looking down the length of trench 7. A geologist uses a metal detector to locate strikes. The basal contact of a conglomerate bed is marked with green paint. A steel sample drum and the 40-tonne excavator used for trenching are in the background.
