In the northwestern part of In unfassen or "the haunted dry river bed which breathes" in Tamashek, is a petrified wood forest which covers an area of two hundred square kilometers. Certain petrified tree trunks are larger than two meters in diameter and twenty meters long. On the road to In unfassen you can see herds of addax gazelles which have survived attacks from all kinds of poachers. This is the beginning of the great plateau of the desert of the Tamesna.
