Mountainous country (6)

I believe the answer is:

massif

(Other definitions for massif that I've seen before include "Mountainous block" , "Geological formation of an IMF ass" , "Highland area?" , "Compact mountainous area" , "Compact grouping of mountains" .)

I've seen this clue in the Sydney Morning Herald.
