Climb: Illumination Rock-SW Ridge
Date of Climb: 6/18/2006
Trip Report: Climbed the SW ridge on I-Rock under full-on rock conditions with Michael Nozel (AKA the Great Iron Monger for his pitoncraftwerk). The day was beautiful and the rock very awful. It may have been up to 5.9 but the easier the climbing, the worse the rock got. Luckily, the gear was good since falls due to broken holds seemed very likely.
Nozel on the first pitch:

We got to the West Gable in four pitches - moving east of ridge crest for the third and fourth (i.e, east of where Wallace has the route on his great topo). Pitches 1, 3, 4 were semi-terrifying due to crap rock but the gear was pretty good.
The best part of the climb was moving along the summit ridge from the West Gable to the true (East) summit = exposed and spectacular!

The overhanging summit block (perched over Michael in pic below) was very cool too, a nice exposed mid-fifth boulder problem.

I-Rock covered in ice is a worthwhile objective (I climbed just east of this route in winter and had a very different opnion of I-rock then) but leave the rock alone!
Jeff Thomas said it perfectly: "The volcanic rock of
Illumination rock is good when compared to the rest of Mt Hood, but terrible when contrasted to what modern rock climbers prefer. Still, to paraphrase Tom Patey, any fool can climb good rock, it takes a special fool to climb bad rock." I would advise against becoming a special fool.
Gear Notes: Nuts, pins, hexes (yes!) and a few cams
Approach Notes: Don't disturb the skiers, they paid and we didn't, damn it.
