Began screening a 3x3m sample of locus 31 in SW corner of trench. Screening a depth of 20cm above the floor until we hit the floor. Sample area is locus 33. Looking for carbon samples as well as material that can tell us more about the function of this structure. Collected a total of 4 small carbon samples, foiled separately but placed in same bag. Ar/Ts.SLT1.33.C14.1-4.
Still going down in locus 25 in northern half of trench.
