Place: Ar/Ts.NT1.A9

This is a harder packed version of A3 - where it was very light and ashy in the former, it is now densely packed right over an uneven clay floor. The clay has been traced out in the southern part of the trench, but does not seem to extend all the way to the north baulk. Bottom elevation is uneven. In general it is lower in the northern part of the trench: southwest corner 2164.562, southeast corner 2164.552, center 2164.252, north center 2164.302.
