In SLT3 decided to go down below floor. Turned out there's still a lot of soil producing a lot of bones. Soil below floor designated loci 5 and 6 for original 1x2 and expansion.
In SLT1 came down on pit (locus 18) dug into locus 16 yellow clay. Pit produced large LBA sherds and continues into baulk so we'll get the rest when we expand north. On southern side of wall construction finally hit an reddish orange clay floor below locus 13. Will continue exposing it tomorrow.
