In 1976, the first expedition organised by the Cerberus SS, we focussed on the major cave systems of Gouffre Friouato and the Grotte du Chiker.
Here is a video posted by an expedition member, Peter Glanvill.
I don't seem to have many photos at all of the expedition -
and the countryside around Taza -
The entrance to Frioato -
Gouffre Friouato is one of the largest cave systems in northern Africa. It is open to the public as a 'basic' show cave. The entrance shaft is 100 m deep. Below are large passages that end in a sump.
See more about Friouato on the Moroccan tourism site. And more photos by Pete Glanvill.
