http://www.summitpost.org/chimborazo/150349 See comments discussion of actual height. It refutes the bad GPS claim. I have also actually been to and climbed the peak in question. The lower elevation cited on the Wiki page is actually for the Ventimillia summit, not the higher Cumbre Maxima or Whymper Summit. Jgross46 (talk) 00:31, 21 May 2012 (UTC)


 * I checked the summitpost link and found nothing in the comments section. Check the additions and corrections section. Viewfinder (talk) 21:07, 24 August 2012 (UTC)

Ok, I copied and pasted the text I an referring to. As I look now the section is titled overview and this is contained within it:

"Many climbing parties had climbed Chimborazo under foggy conditions using GPS devices and getting a measurement of 6,267 m (20,556 ft.). It happened that they reached Cumbre Veintimilla or the second highest summit which actually has that altitude. In a clear day Cumbre Whymper or Maxima is located in the back of it (visible from Cumbre Veintimilla only) and it can be reached after descending and traversing a couple hundred meters in east direction. At the moment the official altitude is 6,310 m (20, 702 ft.) as stated in most of the new mountaineering and climbing guides."


 * I had read the above on summitpost. It contains no verifiable source or hard evidence. Can you cite a report of 6310m being upheld by a modern measurement? See additions and corrections. Viewfinder (talk) 00:58, 25 August 2012 (UTC)

I can site the printed text Ecuador Climbing and Hiking Guide by Viva Travel Guides by Rob Rachowiecki and Mark Thurber copyright 2008 Viva Publishing Network. ISBN-10:0-9791264-5-2 ISBN: 978-0-9791264-5-1

page 149 has the map showing the summits and the heights. Pages 130 and 131 also have the printed text of the same. This is and online to the google book. You can use that to navigate to page 130. It's at the very bottom. The other pages I would have to have some way to scan to you:

This is a link to geology.com. Third peak in the listing is Chimborazo. Shows the 20,703 height:

This one is a link to the Smithsonian Institues site. Lists 20,702:

http://www.volcano.si.edu/world/volcano.cfm?vnum=1502-071

Another site which has mixed inconsistent facts is this about.com link. The header states the lower height, but in the text in the middle of the page (3rd paragraph) it discusses the multiple summits and clearly states the Whymper Summit at 20,702 as the highest point:

Not sure what you are looking for interms of validation or if there is anything I could provide. I'm not finding any recent USGS survey information easily availalbe on-line. I could try contacting them directly to see what is available. Most people do go to the ventimillia summit and seems to get listed as the high point, but in fact it is not.


 * I agree that the 6310m elevation has been and continues to be widely reproduced. But there is no evidence that it has been upheld by any modern survey. By contrast, I have cited two such modern surveys. You mention the USGS, from which SRTM and ASTER GDEM data can be downloaded via its Earth Explorer interface. The highest 3" (90m) SRTM cell on Chimbo is 6259m and the highest 1" (30m) GDEM cell is 6265m. These are more consistent with 6268m summit than 6310m.


 * I am curious about the Fast-Facts site, does Chimborazo really have a crater 820 feet deep? Google Earth has high resolution imagery and I cannot see much of a crater, its summit appears to be flat. The Smithsonian Institute site has many inaccurate heights.

 * Web sites and other authorities copy each other and misinformation gets mass reproduced. What none of them can do is to source and date the 6310m measurement. Viewfinder (talk) 04:35, 25 August 2012 (UTC)
