When I first heard about this accident, I only knew it was on Colchuck and not which route. It did strike me as an odd objective choice for this time of year - even if it was just the Colchuck Glacier route. Now, knowing the actual route, I'm still a bit perplexed. Maybe I haven't studied it enough, but I would expect this route more in the spring time. I'm not making a judgment - am just perplexed.
In my experience N Buttress Couloir seems more popular (also has serious objective risk, especially in winter), and of course there's TC on D-Tail (great after some thaw and melt to fill in the runnels).
Anyways, it's always said to hear about an accident like this. Life is short and fragile.
