This sample was taken from "inside" the walls of the room in T22, in its extension. The elevation is 2296.975, which is higher than any of the floor surfaces so far discovered in the room, but it was sampled because it was inside the walls. (Locus 10 is the inside of the walls of the room in the extension of T22.) Found at 80 cm from W baulk and 160 cm from N baulk.
