More rain the previous evening, although less flooding in the trench than yesterday. We are continuing in the southern portion of E538 as E539 remains too muddy to work. As we attempt to work in E545 with shovels, vessels in E538 below require trowel attention. One example is today's discovery of vessel E548. E538 is angled E-W, rising in elevation towards the shrine. In the operation's southeast corner we are cleaning / testing the shrine 'terracing wall' and cleaning / clearing the carpet of rocks under E504. Rain then closed citadel work for the day and we descended to assist at the kurgan.
