Today we started clearing Ar/G T19. A new datum was established on a large rock in the LBA wall running SE/NW, but has yet to be shot in. In the SW portion of T19, we hit some stained soil, and I decided to leave it until we had finished clearing the rest of the trench. There looks to be a possible small wall running N/S in the western portion of T19. (June 28th, 2010)
