Just a note for the casual reader: the route described as the "easy" traverse, is.....depending upon conditions. Timing is critical. This area ices up, and at that time is VERY dangerous. The problem is, that you are traversing on a steep slope on a route filled in with ice, and a 2,000 or so foot runout. So if you fall in ice conditions, you will have great difficulty stopping with an ice-axe self arrest. I've had proficient friends go this section under these conditions, and it scared the heck out of them. I believe there have been fatal accidents here.
I would think early in the morning, or late in the afternoon, would generally be the worst times.
