Seriously, though, this has got to be one of the most beautiful climbs I have done in Yosemite. It is also one of my favorite chimneys. I had read about it merely as an approach to setting up top roping anchors on Chingando, and I was pleasantly surprised to find the chimney to be clean, bright, fairly tricky, interesting for "only" 5.4 and a fun caving adventure in it's own right.
The Iota chimney is hidden away in the Iota Flake on the forgotten far left side of Reed's Pinnacle. The Reid guide indicates it merely with an arrow pointing at the Iota Flake and the words "The Iota. 5.4 chimney behind". It isn't even listed as a route in it's own right in the guide. Guarded by a gully of decomposing class 3 rock covered in leaves & moss, the approach really isn't too bad if you don't mind a little jungle exploration.
I had approached it at sunset at the end of one day in January, and then again last weekend to finally play around on Chingando. At Eric Gable's excellent suggestion, on the second visit we didn't just climb to the Chingando anchors, but also took the second pitch to the top of the formation. This second pitch was very different in nature from the first pitch, and although is still only 5.4 or so, is also runout and only appropriate for confident chimney climbers.

Hidden Entrance to the Iota Chimney. Just Go Past the Large Chockstone.
Getting in is tricky (at least if you're 5'9" and have stubby wombat arms). There is nothing to grab on the pedestal, and you're just high enough to hurt yourself if you slip out. The wide stem option seemed too insecure too since you had to practically leap over, so on my last visit I found out a secure way to enter the chimney. I kept my arms as chickenwings so that my torso wouldn't slip out while doing the crab shuffle. Once you can grab the back edge just do the floppy whale maneuver as you pull up!

Pitch 2. How High? (40-50 ft) Any Pro? (No)

Looking Down. Maybe I Should Place Some Pro Now?
Optional #4 or Smaller Cam Placement. I dragged some pro all the way up here, so I might as well place something! :-P
It turns out the rapp slings were right behind my head here. Doh! Well the chimney was too wide for secure hip-knee-heel camming here and the rock is pretty slick, so I didn't mind placing a piece 1 ft sooner :-0

The two pitches can be linked but it can be nice to break them up to better see each other. For rack bring 1-2 quickdrawed slings (optional).
