Unless you are a very able and experienced Alpine climber do not, under any circumstances, go to the Tete Blance via this col. It is pretty much inaccessible now as the glacier has receded. I spoke to the guardian today, having backed off the col, and he said it's too difficult early season, and too dangerous when it heats up - loads of rockfall. Either go over the superior, or go up round the back.
Apparently it's been fairly inaccessible for 5-10 years. Pity my 2 year old guidebook didn't mention that...
