Climb a steep slabby face with 4 bolts using smears and edges passing an optional bolted anchor and then continue past one more bolt to the top and another bolted anchor. To descend: either walk off down slabs on the northwest side of the formation (climber's left) or rap the route with a single 60M rope in two (2) raps. Make sure to use a 60 meter rope or longer!

Typically done as a single pitch route but it can also be done in two.


This route lies just left of the classic Mental Physics on the west face of Lenticular Dome.


5 bolts, bolted anchor/rap (all bolts are 3/8")

I just did this route Sunday 2/16/2014, this was my first successful lead of a 5.9 at J-tree. It took me two separate attempts. Very crimpy and yes start is 10m run out above a cactus that looks like it has been landed on more than a dozen times. Wow, I would give this climb four stars though. It is a must do if you are waiting for “Mental Physics” like we were. Feb 17, 2015

Wonderful route with lots of tiny edges.

First bolt is 25 feet up with some tough moves to get to it. Plenty of exposure and a bad place to fall. Might deserve an R rating for this and also for long runout. Dec 11, 2013
Definitely one of the most sustained bolted 5.9s I've ever been on at J Tree. The bolts are FAR apart - Colonel Mustard's comment that clipping a bolt lets you mentally prepare yourself for the climb to the next one is ACCURATE! It's all there. Great stuff. Nov 22, 2012

This was a good warmup to get the footwork dialed. We were waiting on Mental Physics to open up. It was one where you steel yourself for the climb up to the next bolt once you gain the previous. Since the comparison comes up, this is definitely a 5.9 if Loose Lady is 5.10a. Jan 5, 2012
Indeed the first bolt is rather high. The rest of the climb doesn't kick back until the top and even then it's run out but easy. Many of the holds were ity bity but there. The combination of which makes this a fun climb indeed! Dec 16, 2010

Decided not to lead this one, as the first bolt is damn high over a bone breaking fall, 30 minutes from your car. On toprope, I found that the bolts are quite logically placed (just at the difficult parts) and that the climb is pretty cool.

Recommended if you have the balls. Dec 13, 2010

fairly runout, but not to hard for 5.9 Mar 23, 2010

I loved this route. I just TRed the first pitch but the movements were so much fun once I figured them out. The crux seemed to be near the first bolt. Gotta trust the JTree friction. Jan 29, 2008

Great route.....clean rock and a fun safe lead..Fantastic day with JF and KF.... Oct 31, 2005
I think the reason this climb feels harder than 5.9 to some is that (in my opinion) the difficulty stays pretty consistant in the first pitch right off the deck with potential for some nice size falls that someone climbing at or near their current limit will certainly take seriously. Becasue the moves are all there and solid, this factor should make the movement of this climb quite enjoyable for those who comfortably lead at this grade (at Josh) and add to the feeling of adventure for those pushing their limits. The route also rises steeply in an upper section (P1) setting it apart from many low angle slabs whos' sloping character can hide the exposure and the feeling of being runout--something I think very much adds to the route' Apr 18, 2005

I'd give the route a 5.10a. I remember it being quite a bit harder than the advertised 5.9. Maybe it is just the space between bolts. I think I only climbed the first pitch and came down. Feb 6, 2005
I've climbed this route a couple of times. It's a wonderful route; however, I'd rate it 10a. May 13, 2003

As previously mentioned it is possible and even recommended to do this route in one pitch. There should not be any slings left behind as the anchors are all metal hardware. Jan 7, 2003

Edgy first pitch and run-out second to a wonderful summit.

Unfortunately a lot of people seem to rap off after the first pitch, evidenced by a large number of slings which I once removed from the bolt anchor at pitch 1.

A worthy, albeit harder, companion to Mental Physics.

another funroute. seems a little harder than 5.9 Nov 28, 2002
