Continued in topsoil in both SLT1 and 2. SLT2 very cobbly with only apparent construction the S face of a possible wall running SW-NE through W side of trench. Appears to jut diagonally off construction along S wall of trench, so possibly different episode. Stones are taking up a lot of room so we expanded 2x1m to the E.
In ELT1 stayed in topsoil. Easy digging with only a few rocks and low artifact count.
