Today we continued working on T16B. It became clear that locus 2 continues on the Southern edge of the unit. I had to reopen locus 2. I worked in T16A clearing off the paved floor in the middle of the trench and cleaning out the horrible tangle of rocks in the eastern section. It is still tangled. I took 2 macrobot samples from the destruction layer. There are huge chunks of charcoal on top of the paved floor. Less charcoal where there are no rocks.
