Excavating rock art in Strath Tay day 11: Excavating fissures

The day after the storm, we continue to excavate down through the centre of the main trench until we reach bedrock. The cobbles remain unconsolidated. This absence of structure suggests that if there ever was a cairn, it has been seriously disturbed. The fissures at the centre produced few artefacts and no quartz deposits were found there.

In contrast, a series of fissures towards the edge of the trench do contain deposits of worked quartz.

A final clean up of the quartz boulders shows them to be a part of the bedrock, and that they appear to have been shaped into a zig-zag pattern.
