Once a fertile “plateau of rivers,” as the translation of its name implies, the region is now an arid expanse of desert that is inhospitable to the many forms of life previously known to thrive there. Ourahmane, together with a group of collaborators and local guides, journeyed on foot for thirteen days to a part of Tassili n’Ajjer near the border of Algeria and Libya. Both the group’s footage and movement are at the centre of Ourahmane’s exhibition at Mercer Union, which marks the first presentation of her work in Canada.
