Rio Moctezuma: Blind Faith? (Rocky Contos)

I have gathered a great deal of information on the Upper Moctezuma and would like to solicit additional information from anyone that knows anything.
  Apparently the upper Moctezuma has not been floated since the first and second descent parties did it in the 1980s.  Presa Zimapan precludes a run through the "First" and "Second" canyons, which still exist but have no water as it is all diverted 35 km around them to a powerhouse.  It is still possible to run the Moctezuma from a place called La Mora, where the water is released.  The assumption that nobody else has run the section is made based on information gathered from me, Tom Robey (partial 1st descent trip), Ken Vanatta (complete 1st descent trip), and Tom McEwan.  Tom McEwan reported running a section a couple times starting close to Landa de Matamoros (by hiking in  from the north rim; this is about 45-50 km downstream of La Mora and past most of the major chasms and big rapids).  Their trips were 3-4 days to Pisaflores. He reported it being "a great time and a beautiful piece of river", apparently class III-IV.    Dave Brunton also reported running a similar section.
  Satellite images indicate the Gringo Guide's placement of the 40ft waterfall on the upper Moctezuma to be incorrect. Whereas it indicates they are in the "Third Canyon" and below the hydropower plant, actually the falls are upstream.  Tom McEwan concurs, and has personal experience having hiked the section above the hydroelectric facility near La Mora (as a downstream hike).  It is possible to hike upstream to these falls from the powerplant (about 5 km upstream).  Tom Robey also agrees with this assessment.
   So, apparently the section below La Mora has not been revisited for a couple decades.  Although it lacks the 40 ft waterfall portage, there may be worse places in that section (see below).  If you are interested in re-exploring this section of river, let me know since I'll be organizing a trip down this year.  Below is the description from Ken Vanatta. The first two places he refers to are above La Mora (i.e. no longer floatable since there is no water in the river there anymore). The third place he talks about below is a rapid/section that is almost certainly below the powerplant and below La Mora.  I am referring to this rapid/section as "Blind Faith" (a term approved by Ken). Blind Faith is on the part of the Moctezuma between La Mora and Landa de Matamoros.  In addition to this rapid, there appear to be other major rapids in the section within some major chasms with overhanging walls.

FROM KEN VANATTA (1st DESCENT PARTY, MARCH 1985; writing in November, 2008):
There is an incredible house-size boulder jumble pinched within towering, straight out of the river verticle walls somewhere in the first half of the trip that cannot be portage on land. The key is a boat, wedge, and carry tactic through and over the boulders down the middle of the very long rapid. There was no alternative but to go for it and is very risky. It requires wedging your bow in sieves, climbing out across the deck ,without falling into the sieves, pulling your boat up on top of massive boulders, slidding off into fast channels and repeating the task several times before there is a continous exit channel. It requires cat-like agility and a mistake could end in entrapment in torrent sieves. 
The 40' falls is about mid-way. Robey's paddled back upstream a little ways and chose to climb out of a steep, but possible, coulair. The rest of us chose to risk the intimidating portage required. The falls might be runnable, but it is very under-cut and looked probable to trap someone behind it without room to escape. In fact, we had one boat get blown of the cliff by the wind and into the base of the falls. Which, it did indeed get stuck, getting trashed behind the falls, for about five minutes. As you have heard about, our portage was on a ONE FOOT WIDE inclined cliff ledge that angled up and past the falls on the left. We were able to reach a distance about 20' past the reverse-draw of the landing zone and were some 50'-60' above the river where we one at a time would throw our boats in first and then jump off after them. There is a large pool to recover them in.
Probably the most formidable place is somewhere around 3/4 the way through the trip where there is an unscoutable, unportagable, unescapable, and blind class VI rapid that provides no other choice but to risk your life. After picking our way thorugh a long boulder choked entry, like mice in a maze, one or two at a time could fit into a small, middle of the channel, eddy that allowed us to see that the next move was like a nightmare --- the possible end to each of our lives. It encompassed a 50' long, 10' wide (we were in 13' boats), chute that crashed straight into a dead end, exploding into the wall and sieving through a crack at a 90 degrees off to the left. With no other choice but to risk it, one at a time we each went accelerating so hard into the dead end, getting crushed into the wall, flipped, and flushed upside down through the crack to the left. Some of us pulled off a quick roll to see what then was happening next (many of them didn't even roll and some swam). Which, was to quickly be flushed through any of three slots falling another 20+ feet and getting crushed at the bottom of them. I rolled above slots and got in one half-stroke to chose the slot that looked best to me. Others were just flushed where ever they ended up. I am not certain if the far left slot was survivable. I managed to hit the right side slot, I think, and some were washed through the center slot, I think. Amazingly, we all survived. Much to our surprise. Honestly, in that eddy above it we all doubted the out come and expressed our love and thankfulness to our friends as we each departed from sight. Knowing now that we each made it through, and in modern creek boats, I might run it again, but it would still be a crap shoot as to if there were any logs or a change in the sieves since we were there 23 years ago. It is totally blind and leaves no option but to risk it.
