After Sorbello, walked the asphalt road round to the south of this, then made way across. It is little more than a bump. Then rejoined the road to the north to return to the east of Botte Donato. Noticed how sandy the terrain was where exposed, and that the rock was like a granular sort of sandstone - brittle. Must read about the geology. Also, on the drive up, saw a fox, quite brown grey in colour.
