Talk:Columbia Plateau

Fossils
There should be some clarification of the fossils section. that i am aware there have not been any insects found associated with the Columbia basin deposits. Could someone wipe my dildo? Kevmin 22:24, 4 June 2006 (UTC)

Merge
I don't see the relation between the Columbia River Plateau and the Interior Plateau. I have lived in Washington all of my life and am actively interested in the geology of the state, but i have not hear of the Columbia plateau being considered part of the Interior Plateau of British Columbia. I would recommend against merging these articles. Kevmin 03:46, 12 September 2006 (UTC)


 * I agree and removed the template. --mav 00:40, 22 September 2006 (UTC)


 * Did you read the article? It's mostly about the Columbia River Plateau. It's an orphaned fragment, and should be merged. heqs 17:29, 25 September 2006 (UTC)


 * I agree that it is a fragment. It should be expanded into a full article. I do not agree that it should be merged with the Interior plateau.  The Columbia Plateau is of totally different origins.  Do you have references for the inclusion of the CRP into the IP?Kevmin 23:12, 25 September 2006 (UTC)


 * All I'm saying is the relevant content from History of the Interior Plateau, not Interior Plateau, should be merged into this article. heqs 07:48, 26 September 2006 (UTC)


 * Ahh, I understand. I thought that the proposal was to merge all three articles, my mistake.  Yes the relative content from the "history" page should be merged to this and other aprop. pages and it should be made a redirect to the  "interior Plateau" page.  I would suggest a small explanation placed with the merge notices would have helped to prevent misunderstanding. Kevmin 18:04, 26 September 2006 (UTC)

Origin of Columbia Plateau
My geological reference material suggests that 'Generations of geologists' have sort of lumped the besaltic lava flows of the Miocene times as if it were a single event called the "Columbia lava Plateau"   the author I'm looking at  "David D. Alt and Donald Hyndman" in a 1978 work entitled "Roadside Geology of Oregon", prefers to break down the flow in smaller pieces. This appears to be consistent with the green map. He assigns the source of this flow as the 'Grand Ronde Volcano  which he describes as perhaps the largest volcano on earth which put out basaltic flows that made it all the way to the Pacific Ocean. Is this consistent with what others are finding?Rvannatta 01:54, 2 October 2007 (UTC)
 * You may want to look at the slightly similar Columbia River Basalt Group, which includes the Grande Ronde flows. Also, you might want to remove Portland and Cannon Beach. They are on the green of the map, but that is the basalt flows and not the plateau. As the lead says, the plateau is east of the Cascades. Aboutmovies 02:49, 2 October 2007 (UTC)

made the changes you suggested and added the Basalt group as a 'See also'.

There seems to be little question that the Grande Ronde lava flows flooded into the pacific after crowding down which is now essentially the Columbia river. Clearly if one wants to apply a geographical definition to the columbia river plateau then limiting it to east of the cascades is probably ok, but that definition makes little sense in a geological sense.

The recognition of the presence of the columbia basalt is critical to understanding of the geology of the far northwest Oregon.Rvannatta 03:45, 2 October 2007 (UTC)

Map and caption
The caption says the green area represents the plateau, while the map itself says that that's the Columbia River Basalt Group, and the plateau is vaguely defined by the title "Columbia Plateau" in red. So what are the actual boundaries of the plateau? Katr67 04:13, 2 October 2007 (UTC)
 * I fiddled with the lead, but the article still says later that the plateau and Columbia Basin are synonymous. But the basin is the watershed of the river, isn't it? Katr67 04:20, 2 October 2007 (UTC)


 * I think you are mostly right about the Columbia Basin and the Columbia Plateau not being synonymous – although I suspect the terms are often used loosely and in differing ways. I've seen the term "Columbia Basin" used to refer to the general "plateau" area as well as the lands of the Columbia Basin Project. Another term I've seen a bit is the Columbia Plain, or the Great Columbia Plain, the Great Plain of the Columbia, etc. There's even a book called the Great Columbia Plain. The definition in that book is based more on history and culture than on geology, but is fairly close to the "plateau" definition. The author claims the term (or similar variants) was in common usage for a long time before being somewhat replaced with terms like "Columbia Plateau", "Columbia Basin", "Inland Empire", and others that refer to a somewhat similar area. It denoted, according to this book, the region east of the Cascades through which the Columbia and Snake flow, in which there are few trees and in which the land is relatively flat compared to the rugged mountains around it. I can't find an online map of it offhand, but it is basically defined as the region east of the Cascade Range, north of the Blue Mountains, west of the Rocky Mountains, and south of the Okanagan Highland – including the Palouse, Channeled scablands, the Columbia Basin Project area, the Walla Walla region north of the Blue Mountains, the Kittitas Valley around Ellensburg, the Yakima Valley, the Horse Heaven Hills – and in Oregon the agricultural regions south of the Columbia River between The Dalles and the Pendleton area – and in Idaho the Palouse region extending into the Nez Perce area southeast of Lewiston (you can see this region pretty clearly as flatter and lower than the mountains around it on the map on the Blue Mountains (Oregon) page). It seems to me that this general area is often what people mean when they say "Columbia Plateau" or "Columbia Basin" – at least in the United States, and with many variations, like whether the Okanagan River valley is included. On the other hand, both terms are also used in other senses for larger areas. In short, it seems to me that there is a fairly well defined region there that lots of people understand to exist, but without a generally accepted name. Tricky.. (much of the book's definition as well as the notion that modern maps have "lost the region's name" is readable on the amazon webpage for the book) Pfly 05:55, 2 October 2007 (UTC)

I think I agree there is a geographical region probably centered on the Palouse. My problem with the leadin sentence was that it equated the geographical region with the geological region which drives a conclusion that the most magnificant display of Columbia Plateau basalt in the region (Crown Point) is not..... Rvannatta 13:37, 2 October 2007 (UTC)

If I were to propose a 'fix' it would be to change the lead in sentence of the section to recognize that the geographical and geological boundaries of the Columbia River Plateau were not the same. To simply deny that the basalt poured through the Cascade range and into the Pacific ocean while displaying map showing that it did, makes not a lot of sense.Rvannatta 13:46, 2 October 2007 (UTC)


 * Rvannatta, I think you're onto something. If the term means different things in a geological or geographical context, it's absolutely essential that the lead take note of that. Katr's point about the caption is dead-on, too; if that map is used as the main image in the article, people will tend to assume that the large green blob is the plateau, and if that's not the case, that should be made very explicit. -Pete 19:37, 2 October 2007 (UTC)

proposed solution.
the authority I have been looking at addresses the issue in debate somewhat and it makes some sense.

"A large fault just east of Hood River trends from north to south and has raised the country west of it about 1000 feet during the last few million years. The area east of the Hood River fault is noticeably lower than that to the west and it makes a convenient place to draw a topographic line between the lave Plateau and the Cascade Mountains.   The narrow gorge of the Columbia River changes at Hood River to a more open canyon  that extends to the east, lined on both sides by ledges of plateau basalt"

This seems to me to be a reasonable way to resolve the issue. I would therefore propose as follows:

1) the "Geological" be stricken from the lead in. it's wrong. 2) The USGS map caption be clarified to acknowledge that it represents the extent of the Plateau lava flows. 3) That the geology section be 'enhanced' to include at least the first 2 sentences of my quotation, along with an explanation although the plateau basalt extends all the way to the present Pacific Ocean as shown in green that the 'Columbia Plateau or Columbia Basin' which I am inclined to equate as the same,is the portion of that basalt flow east of the Hood River fault.

this probably implies that the city of Hood River should be stricken from the list of plateau cities as well since the 'convenient...topographic line' is east of Hood River  (and probably explains the existence of the Hood River Valley).Rvannatta 01:04, 4 October 2007 (UTC)

Move/rename to Columbia Plateau
"Columbia River Plateau" sounds clunky; apparently it was used because "Columbia River" had been co-opted as a title by creators of the WWF ecoregion article, now titled Columbia Plateau (ecoregion), which I dismabiguated a while back, I believe....."Columbia Plateau" in its most common usage is a LOT bigger than the WWF-defined ecoregion, and I see no reason why the awkward "River" has to be in this article's title any further. it's a simple move, but not simple enough because of the intervening redirect and there may be citation/defintion/usage issues I'm unaware of; I'm too lazy today to start a formal articles-for-discussion rename though that is a recourse if there is no resopnse here.....anyone have any objections, orwaht are other issues?Skookum1 (talk) 13:42, 24 December 2008 (UTC)

name/redirect issue
This shouldn't have to be a disambiguatino page; the term Columbia River Plateau is an artificial construct (a "Wiki-ism") for which the most common and widespread usage is simply "Columbia Plateau"; the Columbia River Plateau page should be a redirect to this page, and the dab for the ecoregion is more than sufficient.Skookum1 (talk) 15:10, 28 January 2009 (UTC)


 * This should not be a disambiguation; this is the official name for the landform and should be hte main title for the mistitled Columbia River Plateau. The EPA ecoregion usage is entirely secondary and derived from this usage, and is not an original usage and can simply be a hatnote.  Adding db-move to this so the plateau article can be moved to this title.Skookum1 (talk) 11:44, 1 June 2009 (UTC)


 * In reply to the speedy remove question: the simple and direct answer is that Columbia River Plateau was mis-titled from day one; someone may have created that name because the ecoregion people had already co-opted the name for their article, but the reality is the ecoregion is named after the landform, and the landform's OFFICIAL name is simply "Columbia Plateau". It doesn't occur in print any other way, except perhaps by people who've used Wikipedia to do their research.  I'd think that's simple enough; the "most common usage" of Columbia Plateau is for the landform, and not for the ecoregion, and the ecoregion name is derived from that of the plateau.  Inventing/creating "Columbia River Plateau", essentially, was original research/synthesis and is not citable.Skookum1 (talk) 21:43, 3 June 2009 (UTC)

Geologic relation to Yellowstone?
i understand, that the Columbia plateau is about the same age, and derives from the same volcanic episodes, as the earliest (Snake River valley) episodes, of the Yellowstone hotspot. Not impossibly, the entire Columbia plateau + Basin & Range province + Yellowstone hotspot track all represent a single vast volcanic super-province, representing the surface effects, of all the intense heat, friction, melting etc. occurring deep under the North American continental crust, as NA obducts over oceanic ( Farallon) plate 66.235.38.214 (talk) 20:09, 29 September 2012 (UTC)

Page rename
I object to the renaming of this article with no discussion. I cannot revert to "Columbia Plateau" (due to technical limitations of Wikipedia), so will request an admin to revert the move. Let's please discuss using the well-established requested move procedure. —hike395 (talk) 02:36, 29 March 2018 (UTC)


 * Please hold off converting this article to be about the valley, at least until we can get consensus around the conversion. This article is about a geological feature. The article Columbia River drainage basin is about the basin. —hike395 (talk) 02:47, 29 March 2018 (UTC)


 * Later: I see that moved Columbia Basin to Columbia River Drainage Basin. All of these page moves and article refactorings really need to be discussed first: I think that Columbia Basin was a good name for that other article, and can be modified to contain more geographical information. This article should be about the geological feature. —hike395 (talk) 02:50, 29 March 2018 (UTC)

Thanks for the notification on my talk page, I just figured "Columbia Basin" was a much better name for the article due to its larger usage, including on this U.S. government site. I also only used the valley infobox because it was used on this article for a similar region (which is labeled as a good article. I was wondering what your reasoning for keeping it at Columbia Plateau was. Thanks again, Howpper (talk) 02:55, 29 March 2018 (UTC)
 * It wouldn't make sense to move that infobox to the Drainage basin article. Why can't the infobox be on this page (regardless of the name)? (talk) 02:59, 29 March 2018 (UTC)
 * My main problem with this article is that right now it's basically just a scaled-down copy of the Columbia River Basalt Group article, when instead that should be exclusively talked about in the geology section of the article. (talk) 03:05, 29 March 2018 (UTC)

I think may be trying to combine two separate topics: the Columbia Plateau and the Columbia Basin. The former is a geological term, which indicates where the area that the flood basalts have covered. The latter has multiple (imprecise) meanings, depending on where the speaker lives. The one precise meaning of the Columbia Basin is the drainage basin of the Columbia River.

(Notice that the Columbia River Basalt Group is the name of the rocks, not the name of the region.)

I think we need to keep these separate and not try to mix them together, otherwise we get self-contradictory articles. For example, the map that Howpper added to this article is contradicted by the map immediately underneath it.

From what Howpper is saying above, he/she think that Columbia Plateau and Columbia River Basalt Group should be merged. I agree with that --- right now, Columbia Plateau is too short, and substantially overlaps Columbia River Basalt Group. : what do you think about that merge?

I would also suggest creating an expanded Columbia Basin article that would be a superset of Columbia River drainage basin plus alternative meanings of the definition of the Columbia Basin. This has precedent: see, for example, Great Basin that discusses six different definitions of the Great Basin! I'm happy to make an attempt at such an expanded article. I believe that expanded article could contain Howpper's proposed valley infobox, plus the map that Howpper has added to this article.

Does this make sense to other editors? —hike395 (talk) 05:43, 29 March 2018 (UTC)


 * Just to clarify, I agree with your above statement; however, I also think there should be a separate article for the geographic, climatic, and floristic region that is commonly referred to as the "Columbia Basin" (which is a separate entity from the Columbia River Drainage Basin).Howpper (talk) 05:49, 29 March 2018 (UTC)


 * I mostly agree: let's convert the disambiguation page at Columbia Basin to a broad overview article. Perhaps where we disagree is that I'm proposing merging Columbia River drainage basin into that broad overview article, not keeping it separate. I'm suggesting that because there's a very large overlap between the two concepts. —hike395 (talk) 11:46, 29 March 2018 (UTC)


 * Strongly opppose. I like the direction this discussion is going, but I don't think we should do anything to the Columbia River Drainage Basin article. Here is a quick map I made showing the Columbia Basin and the Columbia River Drainage Basin. You can clearly see they are complete different entities. What are your thoughts on this? Howpper (talk) 2:19, 30 March 2018 (UTC)


 * Hi, Howpper. I would still like to separate Columbia Basin from Columbia Plateau, because the latter is a well-known and well-defined geological term. See: If you want to turn Columbia Basin into a broad overview article an keep Columbia River drainage basin separate, that's ok with me, as long as you can find reliable sources that distinguish the two.


 * Since there has been no discussion here since April, and particularly as the discussion here is mostly not on the proposed merge of Columbia River Basalt Group but on a possible rename of this article, I am declaring the merge discussion as failed. I won't close this discussion, as you all may want to continue discussing the proper name and scope of this article. If anyone wants re-propose a merge I would suggest new section. &diams; J.
