A visit to several Iron Age hillforts, and a Bronze Age cairn, near the village of Ingram.

Overcast skies towards the end of the day provided excellent conditions for capturing this complex rock art carving in 3D.

At Goatscrag Hill is an array of distinctive sandstone cliffs that overlook the Milfield basin. The walls of an overhanging rock shelter are distinguished by unusual carvings of animals.

Roughting Linn is the name of both an impressive rock art site and a lively waterfall.

The area around Chatton Park Hill is one of my favourite clusters of rock sites in Northumberland.

The light this afternoon was great for creating a 3D model of the cup and ring markings upon a large boulder at Old Bewick.

My first visit to Lindisfarne, also known as Holy Island. The isle is joined to the coastline of Northumberland by a tidal causeway.

I spent the day working with Dr. Sharon Webb, Curator at Kilmartin Museum, photographing a variety of vulnerable Bronze Age artefacts excavated on the Isle of Coll. The images are to be used for a crowdfunding appeal to secure funding to conserve these remarkable objects.

It's been a glorious sunny day in Argyll on the west coast of Scotland. I divided my time between visitingcup and ring rock art around Kilmartin Glen, and landscapes with elemental qualities.

Walker and author Linda Cracknell recently broadcast a thought provoking piece about quartz, and it features my research on Ben Lawers in collaboration with Richard Bradley.

This morning I recorded an interview for the Today Programme on BBC Radio 4. It was about the possibilities offered by visualisation technologies, such as Virtual Reality, for archaeological interpretations of the past.

Last weekend the Royal Archaeological Institute staged its annual conference, The Neolithic of Northern England, at Tullie House Museum in Carlisle.

I recently had the opportunity to experiment with optical projections at the spectacular Neolithic passage grave cemetery of Carrowkeel.

Following our dawn observations at Cuween Hill, Ronnie and I went straight to to the port of Stromness for the return journey across the Pentland Firth.

Our final morning in Orkney was clear and bright, so once again Ronnie and I headed for Cuween Hill to watch the dawn.

After a dull morning at Cuween Hill, Ronnie and I took advantage of some afternoon brightness to go in search of outcropping quartz near the Tomb of the Eagles.

It was difficult to read the pre-dawn skies above Stromness this morning. So, just in case it cleared, Ronnie and I headed out to Cuween Hill cairn in the early hours.

Wild weather continues in Orkney, yet again making our fieldwork impractical. As a break from reading, Ronnie and I went for a somewhat breezy walk along the coastline near Birsay.

Wet and cloudy weather today in Orkney, so Ronnie and I took the opportunity to visit Stromness Museum.

Clear skies over Orkney this morning allowed Ronnie and I to record projections of the solar disc inside Cuween Hill chambered cairn at dawn.
