See that craggy, busted, pinnacle of friable rock on your right as you're driving into Bend from…read morePortland? The one just north of that nipple-looking one*?
That's Three Fingered Jack.
If you happen to live in Oregon and also happen to want to do some *alpine* rock climbing in Oregon, this is one of your only choices. (that nipple I describe above is your other)
The rock quality on both is horrendous. If this rock were in Washington or California, no one would climb it. It breaks, it sheds, it's hard to protect. It reminds me of the Chugach up here in Alaska.
At least the approach is short. Take the PCT north for about 3-4 miles. Eventually, you'll see TFJ (if you want to be seen as kewl by other peak baggers, this is how you should represent this mountain in text). You really, truly, cannot miss it.
Once you see it, pick the least horrible way to hoof it up the loose dirt/gravel/scree/choss and up onto the higher parts of the peak.
Eventually, you'll come to an awkward traverse. This is "The Crawl**".
Some folks protect TC, some folks don't. I climbed it protected because I was new to all things alpine and someone else rigged up all the ropes for me. I didn't find it to be that bad.
Would I climb it unprotected? Maybe.
Should you? I don't know dude, risk management is a personal thing. Maybe you should think about it for a while.
After negotiating TC, you'll reach the summit block.
This pillar of petrified poo is rated at 5.0-5.2 depending on which crusty, old-timey mountaineer you ask. The climbing is easy, but it doesn't protect all that well.
People usually plug some small cams. I'm very comfortable taking a fall on small cams when compared to my peer-group. I don't think the placements here are very good. Remember rule 000001 of climbing: don't fall.
If you're just a hiker, I would NOT recommend YOLO-ing up this fucker in your Keens! This is easy rock climbing, but it is absolutely rock climbing. This ain't no scramble, go back to Chow if you're looking for one of those!
There's usually a whole mess of tat on the summit, so you can rappel back down the small face of portable-chickenhead-hand-holds.
Despite the abysmal rock quality, TFJ is still worth tagging. Once.
Why? The approach is short and the views of Mt Jefferson are stunning. (FYI cool kid: if you want to sound hip when talking about Mt Jefferson, call it "Jeffy". Also: talk constantly about how the only route worth doing is Jeff Park Glacier. But *never* call it that, just shorten it to "Jeff Park")
If you're feeling really freaky, you can also easily attempt TFJ in the winter. The road is plowed. The summit block? It's often coated in beautiful-but-impossible-to-protect rhyme ice. Good luck, friend.
*The nipple is Mt Washington.
**When I lived in Oregon, I found that TC was a good benchmark for gauging the mental toughness of prospective climbing partners. If you want to do this too, it could go like this:
"Hey, you ever climb TFJ?"
"Yeah bro."
"So...whudja think of 'The Crawl'?"
"Fawk brah, that shit was easy! I could've sprinted through it in my Crocs!"
That guy could be someone you want to climb with. He could be a confident, sure-footed climber and a natural leader. Or he could just be a loose-cannon with a deathwish. Use your own judgment. Pay attention to body language.
