Yes there were cornices.
This one was ready to go. The saddle directly above Avalanche Gully.
I had less than fond memories of that exact cornice. Here are two views of the same spot from above. The first was this trip. The seconds was the same spot in 1975 during a rescue. I was part of an MUMC Alpine training trip when we came across a party who had gone over with the exact same cornice location. We didn't start descending till dark and the whole slope had iced. Quite intimidating descent.
Borrow all of them. Particularly as the last is of an actual rescue. Luckily the party that went over (South American) sat on the cornice as it fell, descended and then stopped. Would have been a different story if it had been icier. It would have been a Stephen Galland or Tom Kneen outcome. Those MUMC trips were quite risky in hind site. You should be able to extract the pictures from the flickr site. Let me know if extraction is a problem. Here are a handful more.
The piece of cornice about to go is seen on the left in the saddle in this one. It looks like the break is apparent at the bottom as well.
