These cuts in the bedrock (6305, 6306, 6307, 6308, 6309, 6311, 6312, 6313) were visible upon the removal of geotextile in the southern portion of room G-10. Because we did not excavate the soil layers associated with them it is difficult to determine when they were made. Some appear to be postholes but others are more irregular in shape. This is the largest cut, and might have once been several postholes, or perhaps be related to the construction of wall 6266.
