I have done it.
Loose is a tad on the mild side for an adjective. Horrific pile of crap in variable size from suitcase to VW that constantly spills down, crashing side to side before spitting out into the gaping moat below the entrance is more along the lines I'd use.
The weight of your gaze on each block is just as likely to send it tumbling as actually touching it.....
but thats just me...the guide also says it's become a fairly standard route (or something to that effect)
You cant possibly believe everything you read?
I have no idea where your seeing it from, but after the weather closed in on us, at the top of the gully, we bailed back through the shootin' gallery just fine. Dont expect bail webbing to survive long up there.
Go early enough and you might be lucky enough to have snow the entire way to the ridge.
I'll say no more
