Juan,
That was us, the party of four Mountaineers. Interesting connection. I was the guy who tip toed out on the ice face and got some protection in. It seemed to me to be quite a bit steeper than 40 degrees, but, very good and fun and certainly a top ten climb in the range for me. Thanks for clearing the ropes! Almost vintage pictures? Post!!!!
The face looked much icier this year and looked to have much less snow on it for the same time of the year 6 years ago...but i don't know what are normal variations in snow pack/glacier size. i would guess that the angle of the slope varies year to year depending on the season and deposition.
with regard to warming, the only thing i'm sure of is that tax subsidies for SUVs isn't the right answer!
That was a great climb, and although at the time i wasn't keen about descending the west ridge, it was a very pleasing way to round out a semi-circumnavigation.
