Today we continued with the digging of the trench US 4056 and we found a different part of the same filling. At the same time we started with the excavation of US 4067, a small and rounded hole that cut US 4064, a fill made of gravel and pebbles in a clay matrix in the North-eastern corner of the area. The hole looks like a post hole because of the shape and the depth (40 cm ). We spent the rest of the day helping area 2000, sector B with a leveling action that involved the whole surface of the area.
