Re: geologicTells about the geologic upheaval when the Pyrenees were formed. Rocks of completely different periods now lie side by side or above and below each other.
The same happened on the Carnic Alps main ridge, which (also?) follows the tectonic faultline beween north Africa and Europe. Geologically the mountains are a big mess but nontheless very interesting.
In the Cap de Long area you have the Néouvielle granite, Campbieil schist, Pic Long limestone (I think) and the brown stuff Maou and Badet (or Taillon) are made of. Very diversive ...

Re: geologicIn the case of this section of the Pyrenees it is not so complicated indeed. There is a granitic horst on most of the range, increasingly visible as you go east (west it goes underground in the Béarn); it is almost everywhere the water divide but the Bigorre is an exception: Perdido and friends are just a high limestone edge while Néouvielle makes the heart, and plus another sedimentary "wave" more north (Pic du Midi de Bigorre is part of it). Usually schists make the buffer between the granite and the sedimentary rocks, and the route to Campbiel is interesting as we enter this buffer zone very suddenly. And yes, a limestone "hat" is on top of Pic Long, part of the south limestone rim.
Btw did you know Perdido is Europe's tallest limestone peak 12m above Marmolada ?
