Ixty high spot, 14 million lifetime prominence (with repeats)
- Am forwarding a discussion between Dave Covill and Adam Helman
in the cohp egroup. Some may be interested in
1. Hand level observations on Ixty in Mexico.
2. Mexican Guide Vicente Azpeitia reported to have
climbed Orizaba ~800 times, and Izta ~300 times.
This gives sum of peaks prominence of about 14 million.

This is important news. Suspect that the true top changes over time with
snow coverage - or is this ROCK we are talking about here?
Regardless, "Ixta" is surely tougher than Orizaba.
### Pardon. Both high spots were bare ground now. Snw nearby, but not on
actual high areas, at least 10x10' area on each. I am about 90% certain
that the SE is 3' +/- 2' higher than the NE. i.e. it is between 1 and 5'
higher. The SW spot was 10' lower, and snow covered. Several guys looked
through the level and agreed with what I was seeing, not that they are used
to determining relative elevations by any means. GPS and Altimeter were
useless, varying wildly.
Uncertain WHY guides were needed for the big volcanoes. The routes are
well-known and the climbing issues are well within your abilities to lead.
### Recall we were 12, with varying abilities. No way to herd cats
together on big peaks, we usually were in 2 and sometime 3 or 4 pods on the
way up and down each peak. Hired guides for minimal dollars to watch
laggards, and to escort downwards anyone not having a good day. # well
spent IMHO. Lead Guide Vicente Azpeitia has climbed Orizaba ~800X, and
Izta ~300X. He's 48, been guiding 30 years, guides most every day half the
year and occasionally in the off-season, only guides the big volcanoes. Do
the math, totally logical he has that many ascents. Wow....
- Volcanoes that aren't completely dead could possibly rise or sink slightly, and might change shape enough to move the location of the exact high point to a different part of the crater rim, according to what's going on underneath!

a while back concerning
world 50 peak Klyuchevskaya Sopka:
Etna is also has this issue, as described in Petter's report
- 1) Regarding Iztaccíhuatl, I have followed the very detailed topographic model that INEGI has (National Statistics and Geographic Institute, a federal dependency). The northern point is 1m higher than the southern point of the Pecho (breast) glacier. This is impossible to measure with a commercial GPS.
2) Regarding Vicente, the claim is probably false. The owner of the company hat he works for made an estimate of "up tp" 50 climbs in the 5-month long high altitude season, plus about 10 or 20 more out-of-season climbs. This makes 60 climbs per year for a 3-year period that he has guided. Before guiding, he has about 20 years of climbing experience but his boss said that the figure was wildly exaggerated (hard to even afford all those trips).
