Laid out large expansion of SLT1 on both sides of fortification wall as well as east towards fortification wall corner. Total dimensions of trench now 13m N-S by 11m (max) E-W. Continuing to keep northern and southern sides of the fortification wall separate loci, so topsoil south of wall is locus 24 while topsoil on north side is locus 25.
Further exposure of smaller wall south of fortification wall confirmed its wall status, so it is now locus 22. Carbon sample collected from above one of the wall stones (Ar/Ts.SLT1.13.C14.1).
Cleaned a column of soil in SW corner of fortification wall to expose the wall's rounded corner. These soil strata are loci 21, 23, and 26.
