Basically, I-Rock is a house of cards, and the loose stuff can be BIG! The South Chamber route is "relatively" stable, and protects fairly well. We had a good climb, although I don't think I'll go back. I guess it's one of those you have to do once.
As for the "easy and exposed or dangerous and majorly sketch", I'd say it's somewhere in-between.
I'll make an attempt at putting together a route page.
It would be cool if you did try to cobble together a route page. Something a little more current and detailed than the Oregon High pages would be helpful. I know what you mean about climbs you probably wouldn't repeat (particularly right after you got back safely) but feel like you need to do once anyway. That is kind of how I am about I-rock.... just want to check out that rotten looking pointy bastard up close and personal and do it without getting in a jam.
