In WSL, the entire day was spent working on the pit. First we removed the rocks of locus 5 and then I changed to locus 12 in the same footprint as locus 5, just to get a clean locus for the SW part of the trench (since I suspected locus 5 was slightly corrupted by locus 8 materials.) Worked all day in locus 12, bringing it down to the level of locus 7. Found very large quantities of bone and much ceramics too. Also found two groundstones and another stone that might be worked but we'll see later after it's been washed. In general, the pit is very large now, lined on all sides by the clay and plaster. From the section of the pit it seemed that there were at least two successive silt/trash deposits then sealed by thin levels of packed clay. Created a fourth datum in this trench. It's 2138.813. In WSAR we changed to locus 5 to mark a packed clay just above bedrock, perhaps the floor. No materials in locus 5. Took final photos here after cleaning.
