The final day of the excavation. We complete the digging and recording, reflect upon possible interpretations of this unusual site.

Today we fully explored potential features in the main trench, seeking to determine if a prehistoric cairn had been built on the outcrop.

Storm Ali has been forecast to hit Scotland with strong winds and heavy rain this afternoon. We work on the site until conditions become impossible.

Most of today was spent recording features before we can excavate further.

A grey day, but we continue to try and determine where we are seeing a prehistoric cairn, or the remains of later activities.

The new trench below the rock art is completed and the possible kerb stones begin to look ambiguous.

As the excavation begins to take shape, we expand our digging to either side of the cup marked rock.

The trench has been prepared for recording.

Another bright day in which we trowel back the trench and are visited by rock art doyen, George Currie.

A bright and sunny day. We continued to tidy up the main trench revealing more cobbles and a cup mark.

The weather this morning was blustery and changeable, and we continued to remove the grass and turf from the largest trench.

In September 2017, I excavated for two weeks at a rock art site in central Scotland, as reported in this Journal. One year on, and our small team is back to continue our investigations.

In the midst of a heatwave we backfill the two remaining trenches.

It is our final day of excavation and various tasks have to be completed before the trenches can be filled. Stan Beckensall visits.

Work continues towards the conclusion of the excavation in a couple of days time.

Trenches 1 and 3 take centre stage with new motifs and stone deposits.

Today, the site is visited by a specialist to assess its potential for Optically-Stimulated Luminescence dating. On the theme of light, I also make some observations about the qualities of tree shadows on this sunny day.

On the sixth day day there are significant developments in Trench 1, with more rock art being revealed and the discovery of some very distinctive artefacts which may have been used to carve the motifs.

Trench 1 begins to reveal some exciting features.

On the fourth day of the project we continue work on all the active trenches.
