In reply to drchristinenz:
I didn't find any water. I carried loads, intending to stay in the Bivacco, but when I got there there was still loads of daylight and there were two vaguely hostile lads already in residence, so I gave them a big bottle of water and continued all the way back to my car. By the time I got back I was massively dehydrated and really regretted giving that water away.
