Sounds like you should find and add one then. This isn't a commercial product, it's an open-source dictionary. Halogenated (talk) 17:27, 14 January 2019 (UTC)

replies: text:  The introductory paragraph states that the shield "also includes most of Greenland and extends into the United States as the Adirondack Mountains", but neither are indicated on the map.  How is this ?  —Preceding unsigned comment added by 24.17.110.63 (talk) 18:03, 14 December 2007 (UTC)
replies: text: Because the map is generalized, and because some would define the shield geographically (Canada), whereas the statement that it includes Greenland and the Adirondacks is a reference to the fact that similar rocks underlie those areas.

message: *I just made this series of edits to 'unconfuse' the sense between the shield and a craton... which was the sense before I fiddled.
*These distinctions should be checked by a geology expert.
*If the 'CS' is part of Laurentia, then logic dictates that the 'shield' should not be confused with it's 'foundation', the craton.
:*From the context(s) it seems to be the shield is defined as that part of the craton that was glaciated, not the rock itself, the subject of the craton. Or so I surmise, as a poor humble engineer who's never taken a geology course.

thread_title:  Just a note 

message: I have proposed merging Ancient Mountains Of The Canadian Shield into this page because it appears to me attempting to be a page about, well, the Canadian Shield as a whole. It might be better if it were re-written to be about the mountains - but I know nothing about the subject so have no idea how plausible this is. I'd appreciate opinions from people more in the know! --JennyRad 17:06, 6 July 2006 (UTC)
replies: text: If it was up to me, I would just delete Ancient Mountains of the Canadian Shield - there is no useful specific content other than the idea of 12,000 m mountains (no idea how they were able to quantify that) and perhaps the fact that there are diamonds in the Precambrian rocks of the Canadian Shield, which is already mentioned.  The rest is just generic stuff in my opinion. --Geologyguy 18:01, 6 July 2006 (UTC)

thread_title: Proposed Merger

message: The caption Typical Canadian Shield: pines, lakes, bogs, and rock is maybe a little misleading. For one thing, the trees in the foreground may be members of the Pinaceae, but they aren't actually pines. (I do see some pines in the background of the picture.) For another thing, coniferous forests are typical only of the southern half of the Canadian Shield--the northern half(more or less) is mostly rock and tundra. Granted, the landscape in the image is typical of landscape in the portion of the Shield that's most familiar to the largest number of people. I'd prefer a caption like "A typical landscape of the southern Canadian Shield." 65.213.77.129 (talk) 20:21, 23 June 2009 (UTC)
thread_title: Typical Canadian Shield photo

message: I don't understand what the photo "Canadian Shield Landform," prominently located at the top of the infobox, is supposed to represent. The word landform, as I understand it, and as it's defined in Wikipedia and elsewhere, is a generic term for any conspicuous topographic feature of the earth's surface, like a mountain, plateau, valley, etc. This photograph looks to me like a place where a few feet of land has been cut away to build a road, and as such it could have been taken at any of a nearly infinite number of locations in the world.
I don't understand, first of all, why it is referred to as a landform (If so, what type of landform is it, part of a very low hill?), and, second, how it provides a distinctive and meaningful representation of the Canadian Shield, which it should do if it's going to be placed at the head of the infobox.
The only relevance I can think of is that it shows a very thin soil layer over the bedrock where it's been cut away for the road, which I understand is typical of the Canadian Shield. But if that is this photograph's only significance, it would be much more useful elsewhere in the article, with a more explicit caption calling attention to the thin soil. It might work well in the Ecology section as an illustration of the lead sentence:
:The current surface expression of the Shield is one of very thin soil lying on top of the bedrock, with many bare outcrops.
However, it does not illustrate bare outcrops, since the bedrock here was pretty obviously exposed by a road-building crew, not a glacier.
If this photograph does represent the Canadian Shield in some comprehensive way that I just can't see, somebody please explain it to me, and try to improve the caption so the photo's significance will be clearer to people like me.--Jim10701 (talk) 08:02, 22 October 2009 (UTC)

thread_title:  Historical information 

message: Quote:
The Canadian Shield is part of an ancient continent called Arctica, which was formed about 2.5 billion years ago during the Neoarchean era. It was split into Greenland, Laurentia, Scotland, Siberia, East Antarctica and is now roughly situated in the Arctic around the current North Pole.
I'm no expert, but that seems to be a bit unlikely, Canada, Greenland, Scotland, Siberia, and East Antarctica forming an ancient continent? Is it documented or a mistype?

thread_title:  External links modified 

message: This is rather incoherent. We have "The boreal forest area gives way to the Eastern Canadian Shield taiga that covers northern Quebec and most of Labrador"; but for "boreal forest", the wiki entry reads "Taiga (/ˈtaɪɡə/; Russian: тайга́, IPA: [tɐjˈɡa]; relates to Mongolic[1] and Turkic[2] languages), generally referred to in North America as a boreal forest or snow forest..." (yes, it is redirected to "taiga"). So, going east, boreal forest gives way to taiga, or equivalently, taiga gives way to boreal forest. And a little later we have "boreal forests that give way to taiga in the most northerly parts". This way lies madness, eh? 2001:56A:F0E9:9B00:154F:E1BC:6203:D915 (talk) 03:25, 3 November 2021 (UTC)
