Does anyone have a definitive location yet?
Most reliable info is from the statement by the French minister of transport who overflew the accident site. The statement put the accident near Prads-Haute-Bléone. There is the steeply rising massif of l'Estrop (2961m) to the NE with several ridges and peaks rising above 2700 metres. Judging from the flight path the aircraft would have hit the SW slopes.
Update:
The location is confirmed as le Vallon de Galebre, a steep cirque along the SW face of l'Estrop.
