Around lunchtime, our good friend George Currie drops in to see how things are going. George has found enormous numbers of new rock art sites across Scotland, so we ask him to take a look at some of the possible examples we have uncovered.

By the end of the day, we have completed the first clean back across the trench. This has revealed a scatter of cobbles, the edges of which appear to be defined by stones. Some of these stones are rich in white quartz.
