The Atlas Mountains are a mountain range in Morocco, Algeria and Tunisia. The range can be divided into the High Atlas (or Grand Atlas) of Morocco, the Tell Atlas near the coast and the southern Saharan Atlas.
The Berbers(or Amazigh possibly more properly) seem much more relaxed regarding women and Islam. Women are often seen on the street. It is said that the form of Islam practiced in the rest of the country never penetrated fully into the High Atlas, and all the attempts throughout history to invade the mountains have failed at least in part.
Other points to note:
Berbers are discriminated against quite heavily in Morocco (consider the symbols and papers they need to get into Fez, etc... - is that still true?)
In the High Atlas, in general fewer people speak French than in the cities.
