This is a one pitch route that begins from the top of the flake that marks the start of Pear Buttress. It can thus be used as a start to Loose Ends, Pear Buttress, or Visual Aids. From the start of Pear Buttress, scramble up around to the left to get up to the top of the flake, or start from just below the top on the left. The route begins from the middle of the flake and follows two very thin but good cracks up to the sloping ledge of the three above mentioned routes. Small nuts work really well; small cams are bomber at the crux but plug the crucial locks. NOTE: while it is possible to start up the flake of Pear Buttress and traverse left on its top to the route, I can't recommend this, as the rope drag will likely pull your shallow stoppers out of the rock, leaving you to solo 5.10 slab moves until you can get that TCU in (as happened to a regular partner of mine when he attempted this). I recommend continuing with Visual Aids and Cheap Date for a challenging route with 3 pitches of exquisite, mid-5.10 finger cracks on perfect rock--an unheralded link-up that is one of the best routes at Lumpy Ridge.


Small stoppers (including RPs), small camming units, and a #3 Friend.

Easy to link 1st pitch of Pear B & ThinIndependence (TI) and quite the contrast all in one pitch, of course don't place pro to high at the top of Pear B.

A real pumper placing pro on TI, a gripping lead and another must do Lumpy 10c. Jul 3, 2011

Thought this route was great.... You can easily do the first pitch of Pear Buttress and then just set your belay below the dual cracks of Thin-d, no rope drag to pull u off.... Bring RPs if you like to sew it up.... Enjoy! Oct 10, 2010

Easier than Visual Aids, at least if you try to continue straight through and upward as a 40M pitch. Jul 4, 2008

What a great pitch, very high quality. The gear is really good so I would recommend not wasting your energy placing to much gear since there are no good rests. Apr 24, 2006

Real hard to lead clean. Much harder than some other Lumpy 10c's I've done. Lumpy is hard in general. Like Joe, I used almost all nuts on the hard part--a green Alien in the right crack and a bunch of brass in the left crack. Sep 25, 2004
Placing small nuts alleviates the problem of plugging up your fingerlocks with cams. There is a good nut constriction every 4-5 feet in the first 30 feet (crux). Gear beta (don't read if you don't want it): I almost emptied my rack of all nuts in the #2-#4 BD stopper range in the crux first 30 feet, and didn't place a single cam. Aug 4, 2003
Kind of a taxing lead (placing gear in your only holds), but man, it is sweet. It needs to longer. Take some small RPs and small TCUs or a green Alien. Jun 27, 2003
Did this today 5-6-01 with Charles after a morning of climbing in Boulder Canyon. I wanted to mention that like Chucky said, avoiding the Pear Buttress flake is a good choice. You can start the route by 4th classing up a little chimney to the left of the flake. Have your belayer perch on the top of this big block with his/her feet pressed against the slab. Comfy little spot. The leader can continue around the left and up an easy slab to the start of the route.

A fun TR (or no pro) variation to the start of Thindependence or Pear is the 5.9+ slab directly below the twin cracks of Thindependence. Staying on the lefthand margin of this face (utilizing the arete once or twice) is a great 5.9 face line with perfect crimps. Jan 1, 2001
