With warmer weather today (thankfully!) we are cleaning the walls and floors of the shrine. We have also completed the cleaning of the possible terrace wall on the (south)western side of T2 (E505) and taken pictures. After another backdirt collapse significant time was spent moving the pile to the south. We will need to expand the trench further to the (south)west or to the south in order to distinguish between wall-fall and potential self-reinforcing boulder courses in this 'wall'.
