No, Adara is not sleeping at work. She is excavating a deep post hole. It is 67cm deep and has to wedges.
But the most interesting is that, although about 20 meters away from the circular structure, this post hole might be related to it. It is aligned with the central post of that structure in the alignment that splits the structure in the middle. As you can see, Sívia is in one of the extremities of the overture of the structure and Catarina is in the other. The alignment between posts is in the middle.
And because in Perdigões nothing is simple, ditch 13 is now showing a bifurcation.
