Talk:Canyon

Begin Talk
I got the impression from my school geography books that a gorge has a river running though it while a canyon doesn't have one. Does having (or not having) a river make any difference to the definition of the terms canyon or gorge?


 * I dont think so, there is a river running through the grand canyon and the elora gorge, and most gorges/canyons at one point had rivers or streams running though them to create them.say1988

As far as I know, gorge is the more common name in canada, though the article makes it sem canyon is. At least in southern ontario there are a number of gorges, erlora gorge for example, and no canyons that I know of. Also what is a ravine? it is redirected here, is it a sinonym (jmkijkjkjty6gfthe same thing) or is there something tht makes something a ravine? say1988 14:51, August 3, 2005 (UTC)
 * presumably gorge redirects here, but I noted while looking something up that Chasm redirects to Rift, which isn't right; IMO it should redirect here, to canyon.Skookum1 (talk) 17:48, 21 February 2008 (UTC)

Valles Marineris
Is it possible one could put in an image of this canyon on this page as well? If that is okay, how would I add the image along with the other pictures of the canyons? — Preceding unsigned comment added by FatalGravity (talk • contribs) 18:02, 29 July 2014 (UTC)

English canyons
Re: "Canyons often form in areas of limestone rock. Limestone is to a certain extent soluble, so cave systems form in the rock. When these collapse a canyon is left, for example in the Mendip Hills in Somerset and Yorkshire Moors in Yorkshire, England."

I've left this in place but I have misgivings about its accuracy or usefulness (even after I've changed the obviously incorrect Yorkshire Moors - not a limestone area - to the intended Yorkshire Dales). Does a strict definition of canyon include collapsed caves? Cheddar Gorge - presumably the intended example in the Mendip Hills - is (according to the Wikipedia article) not a collapsed cave anyway. What examples are intended in the Dales? Gordale Scar (also not, according to its article, a collapsed cave)? If these count as canyons (which I doubt) direct references would be more useful.

Sorry, what is sonoma in the beginning of the article?

what affects things around Canyons

Deepest
By what measure is the Tsangpo the deepest gorge? I'm tempted to remove or drastically reword this unless there's a cite. In terms of the measure I just added (depth below highest peaks) it does not beat the Kali Gandaki. – Spireguy 23:44, 14 December 2006 (UTC)

'''what concerns me is that a popular choice as the worlds deepest Canyon the Cotahuasi Canyon a depth of approx 3354 meters isn't even mentioned, the title isn't specific enough does this include the Mariana trench? - Oct 2012 ''' — Preceding unsigned comment added by 92.12.68.231 (talk) 20:05, 3 October 2012 (UTC)

Defile = Canyon?
Why does the Defile page redirect to the canyon page? Shouldn't defile get its own page since it has two vastly different definitions? Chris37599 (talk) 13:02, 7 December 2007 (UTC)

What evidence is there that defile is ever used in the UK? After 55 years of living and travelling around the UK, and being a lapsed FRGS, I have never heard that term used. 143.159.64.177 (talk) 11:25, 26 December 2017 (UTC)

List of canyons and gorges needs splitting off
The lists in the article need splitting off to a separate article, and I don't see the point in distinguishing between gorges adn canyons because the meanings vary and are largely indistinguishable; the third section "things that ahve canyon-like features" is a useless designation; some river-articles will or do have the canyons and gorges categories also, e.g. where there is no reason to have a separate canyon article from the river one, e.g .Cayoosh Creek, Bridge River, Chehalis River, where the river definitely has/ is in a canyon but there is no formally named canyon, or no need for a separate article. The lists are also VERY incomplete...the discussion of gorges vs canyons is highly specious and subjective and should be just deleted, and there are so many ways a canyon can be formed that trying to define them by formation is really quite useless and also constitutes original research.Skookum1 (talk) 15:00, 27 November 2008 (UTC)

Palo Duro canyon
The Palo Duro reference links to an undefined page. This is most likely an intended link to Palo Duro Canyon, but that is in Texas, not Arizona, and there is no record of Pueblo activity in Palo Duro Canyon. Perhaps this sentence should be removed? Ityllux (talk) 04:53, 9 February 2009 (UTC)

There's a canyon in Usak, TR. It's the second biggest canyon on the world. Not eighteenth or seventeenth... —Preceding unsigned comment added by 78.179.177.238 (talk) 18:23, 9 May 2009 (UTC)

box canyon link
The box canyon link just takes you back to the top of the canyon page. Do we not have a page for box canyons? 65.121.141.34 (talk) 18:57, 1 July 2009 (UTC)


 * Apparently there is no dedicated "box canyon" page. It's just a re-direct to canyon. I changed the "box canyon" link to italic text. Takeaway (talk) 11:30, 2 July 2009 (UTC)

Contradiction between this article and Ravine
The opening sentence here defines a canyon as a type of ravine. However, Ravine defines a ravine as separate from a canyon. Which is correct? Kansan (talk) 16:52, 25 March 2011 (UTC)


 * My dictionary of geography defines a canyon as "a steep walled gorge, ravine or chasm cut by river action in which the depth considerably exceeds the width" and "common in areas of low precipitation". It also says "some canyons are produced in limestone terrain by the collapse of roofs of underground streams".


 * So a "canyon" appears to be a type of "ravine" and should be a separate article. I am also not convinced that "gorge" should redirect here as it is defined as a "deep and narrow chasm with rocky precipitous walls" whereas canyons can be on a much larger scale. There is also a regional aspect to this: in that "canyon" tends to be used in arid regions, especially in the US, whereas the term gorge occurs more generally.

Europe is not a country
Europe is not a country. Did you know that? It seems you don't, whoever wrote the list of canyons. Why does it say "Blabla Canyon, Kosovo, Europe" but not "Grand Canyon, Arizona, United states, Northern America"? Skärpning! Fix it. — Preceding unsigned comment added by 85.228.159.25 (talk) 13:19, 30 July 2011 (UTC)


 * The reason why only Kosovo is the exception in this list is because of the status of its international recognition. It is not (yet) recognised by the UN but at the same time it can hardly still be called part of Serbia after Kosovo declared its independence. The present wording in this article is a compromise reflecting the situation concerning Kosovo's status. - Takeaway (talk) 13:45, 30 July 2011 (UTC)

Table?
These lists are silly? Why separate things according to the name ascribed to them (canyon vs. gorge) if there is no difference as per the article text. Could this list be presented as a table, affording some summary information about each and sorting abilities? Canyon dimensions are vague owing to unclear start/end locations varying depths, and so forth, but an approximation would help. Columns could include name, location (text), coordinates near center (geo tagged), length, depth, volume, and slope.

Please define canyon
The article currently starts this way:

A canyon (occasionally spelled cañon) or gorge is a deep ravine between cliffs often carved from the landscape by a river.

But the wikilink to "ravine" starts out by saying

A ravine is a landform smaller than a canyon....

So what on earth is a canyon. There is a newly discovered canyon on Greenland in the news today that is apparently the largest on earth, but I still have no idea what the definition of a canyon is.68.144.172.8 (talk) 13:06, 2 September 2013 (UTC)

Lists section - Split proposed
The "Lists" section now includes more than 140 canyons, and it forms what I think is a disproportionately large part of this article. (The rest of the artictle has only about 60 lines of text). I suggest that this list section should be moved to the article "List of canyons", which currently redirects to the "Canyon" article. Then the redirect should be deleted.

 * Good work. Thought you'd move them all, or almost all of them, along with the related images. If you're planning to keep a top 10 most notable per continent, here are my top picks:
 * Americas: Antelope, Canyon de Chelly, Canyonlands, Escalante, Copper, Grand, Niagara, Royal Gorge, Waimea, Zion (have visited all these & many others not listed here, but missed Copper)
 * Australia: Carnarvon, Geikie, Karijini, Katherine, Kings, Murchison River, Palm Valley, Purnululu & West MacDonnell National Parks (have visited all but Kings)
 * No opinion or experience with canyons in the other continents. Brian W. Schaller (talk) 04:35, 1 November 2016 (UTC)
