Today I worked on the fourth current trench -- they are in a row, every other square meter. The trenches are proving to be difficult with huge masses of an old, fossilized coral reef that we have to dig around. The layout of the site is somewhat like Battleship, or for the younger among us, like real-life Minecraft.
It is set up in a 10m x 10m grid, with the N/S labelling 1-10 and the E/W labelling A-J. The grid itself is labelled "A." Each trench has a label or two letters followed by two digits; AA01 for example. Within the trench there is an additional number corresponding to the locus -- in this case which layer of soil. Since some of our strata can be rather thick, once past the topsoil (locus 1) we dig in 5cm deep "spits." An entire label might be AE06 /5 -- Grid A, trench E06, spit 5. This system allows us to determine any patterns of our finds, such as all heavy objects down hill, which would suggest tumbling or very few small objects in the upper spits, which would indicate wind erosion.
