sooo.....are you back from the 'supermarche' ?
Oh LOL, totally forgot.
Comes from 'le haut du champs', the height of the fields.
Comes from the old-French word Aspera, meaning rocky area.
Peyre should be old French for a monument on a mountain, sourde should be Occitan for damaged/broken.
Aubiscou is the French-Basque name for a plant used to feed cattle and make chimney brushes. This plant grows on the Aubisque.
Bad detour. Comes from the 18th century when people where forced to pass this mountain to reach the Luz valley because the Gave de Pau was flooded. There are other explanations.
Non Pyrenees or Alps:
-Puy de Dôme
Puy means highland or mountain, all volcanos in the Auvergne are named this way. Dôme comes from Gallo-Roman god Dumias.
Venteux should be the right one.
There are other explanations pointing to Vintur, the god of the mountain top or Celtic Ven-Top meaning Snowy Mountaintop.
Since the Latin names Mons Ventosus and Mont Ventorius were also used with ventus meaning wind, it's probably the easy one
-Ballon d'Alsace, Grand Ballon, Petit Ballon
Belchen in German. The Ballons are the high points in the area. Has nothing to do with the shape of the mountains. Belchen was probably wrongly translated as Bälchen.
Could also come from Celtic god Bel. There are theories that the Ballon d'Alsace was used for a solar observatory by the Celts.
That's what I've got. Could be a bit off on some, but I think most is correct.
