Kathleen identified reddish brown strata seemingly cut into fill 16033; at first I believed it might have been a post hole, but after further inspection of profile, 16041 represents the top fill of cut 16032. A rectangular cut was made into 16029; then 16033 a grey fill packed with tile and cobbles was laid on top of which was stone 16036. The space between cut and stone was filled with 16041 up to the unfinished section of stone 16024 covers.
