Left from Refuge des Ecrins at about 5 am in the morning and reached the summit at approx. 9 am. We had to wait a little bit for the last (rocky) part as another group was descending when we arrived and the summit cannot exactly host a lot of people (sorry for the cordée jut behind who we kept waiting!).
Wonderful weather with great views.
From there straight back down to Ailefroide.
Route Climbed: normal from glacier Blanc Date Climbed: aug 1980
Fine weather, after an ugly night in Ecrins hut (room for 120, but 300 persons were present...!). I should have choosen a bivouac on the flat medium glacier, like the 159th Alpine Battalion, whose soldiers had a quiet night !
