This cut in basalt road 4010 is not yet completely excavated (fill 4042) but it appears to be a type of road robbing trench for the basalt paving stones. The bottom of the cut ends at the bottom of the basalt paving stones (the layer on which the stones sit--preparation layer probably equal to 4046 N of the basalt pavers). On the E, the cut is bounded by a line of tufo stones, perhaps to contain the fill 4042. Remainder of fill 4042 to be excavated in 2012. Cut photographed in 2011, but to be shot in in 2012.
