In reply to Groundhog:
The sheep can be quite a problem, best try to bivi away from the good grazing areas.
Once , just above the station, a few parties were sorting out gear. A sheep, waiting for an opportunity, ran off with a large bagguette, then ate it in ( a long) one go. I thought it was going to choke but managed to keep going, probably no choice Quite impressive. Though the look on its eye suggested panic.
Good spots near lac bleu as suggested above.
