Beginning in 1997, the joint British-Egyptian-Norwegian Gebel el-Asr Project undertook archaeological and geological fieldwork in a region of gneiss quarrying and chalcedony mining roughly 70km north-west of Abu Simbel in southern Egypt. In 2012, I joined the project for a brief archaeological survey of the cairn-shrines at the Stelae Ridge chalcedony mines at the north end of the quarrying region, in preparation for a landscape analysis of the site which I undertook as part of my PhD research.
Archaeological surveyor and GIS specialist
Archaeological survey and landscape analysis







Over two days I undertook a total station survey of the Stelae Ridge area, recording the surviving cairns, areas of modern activity, major mines, and some of the peripheral cairns. I downloaded the data and created a plan of the site, to complement existing handheld GPS data and satellite imagery.
I also made a personal record of my experience of visibility at the site through panoramic photographs and a drawing of the ‘circular view’, a sketch drawing of what was visible 360 degrees around the site in the near, middle and far distance. This would inform discussion of visibility at the site, providing a more human-centric counterpoint to the algorithmic process of GIS-based visibility analysis (also known as ‘viewshed analysis’).

Acknowledgements
I am grateful to my PhD supervisor Ian Shaw, Liz Bloxam and Ashraf el-Senussi my fellow team members in 2012. We would also like to thank the Egyptian Ministry of Antiquities, who gave permission for the research at Gebel el-Asr, particularly the Aswan and Abu Simbel offices and our inspector in 2012, Mr. Tahseen Mohammed Atteya Abd El Motaleb, whose hard work ensured we were able to undertake the survey at Stelae Ridge in 2012. I am extremely grateful to the University of Liverpool’s PEET travelling prize fund, the Seven Pillars of Wisdom Trust and Molly Houldsworth for funding for this project.
