English: The deposits were laid down in the lower part of the valley of the Rigarda river, a right-bank tributary of the River Têt. The exposure here is at an altitude of 270 metres, about 20 metres above the level of the river today. The watercourse is fed by headwaters rising at around 1200 metres. The 1:50,000 geological map puts this exposure on the boundary of Quaternary terraces labelled as Fx and Fy, which would mean that the deposits were laid down by the river within approximately the last 200,000 years.
