Sorry, but I've never seen "Montagnes du St-François" used, and Google comes up absolutely blank on that phrase and its variants. Maybe you can find a reference to prove me wrong. Otherwise, I'd say that giving that as an alternate name is as relevant as offering Горы Святого Фрэнсиса or whatever. Yes, the name Saint Francois is French, and the area was part of New France once upon a time, but it simply is not known as Montagnes du St-François anywhere but, perhaps, in France. It belongs in fr.wikipedia.org only, IMHO. The state was once (or twice?) Spanish territory, too, but there's no reason to offer Montañas de San Fransicso as that's equally absurd. By analogy, the Gulf of Mexico article does not offer Golfo de México just because "Mexico" is in the name – the Spanish is used only in the Spanish Wikpedia article.

The Photo, this one taken from the wooden walk plank off of Taum Sauk, is not very impresive. Down the Path there are several outcroppings and clearings that make a more impresive photo and gives a truer sense of the area.
Also a Photo From the Fort Davidson or closer to the base of Pilot's Knob would make a better photo than the one here.
The article is getting heavy on facts, which is a good thing, but there are no citations to back them up, which is a bad thing. Unfortunately, my son leant my copy of Unklesbay & Vineyard to someone who never returned it. -- Kbh3rd talk 04:27, 23 January 2009 (UTC)
I intend to make yet another map for this article, based on some of the same layers that I used for this one for the Ozark Trail article. I mean to make further changes to it for that article, as discussed on the talk page of that image, and suggestions relevant to that use are welcome there. If anyone has suggestions specific to what would make a good map for this article, please leave them here. E.g.: Omit towns? Omit counties? Add Salem Plateau and Mississippi Embayment labels? Thanks. -- Kbh3rd talk 02:02, 8 February 2009 (UTC)
Well, I said "see talk page" in an edit summary, so I guess I should put something here. I was going to question iron in these mountains, but then I remembered Pilot Knob and Iron Mountain, et al. I guess it was the lead belt that got me confused, but there has definitely been iron production in the SFM area. I was thinking of Maramec, Sligo, Moselle, and most significantly Pea Ridge, which are all north of this region. I stand (self-)corrected. -- Kbh3rd talk 04:13, 9 June 2009 (UTC)
So why does the lead sentence use Saint Francois Mountains but the article is called St. Francois Mountains? The official name according to the USGS GNIS is Saint Francois Mountains. The Saint Elias Mountains are not abbreviated in the title. I think this article should be named according to the GNIS. RedWolf ( talk) 04:22, 9 June 2009 (UTC)
There are some issues with the way formation of mountains is talked about here that probably could use clarification. The date of the current uplift of a mountain range can be different than the actual rocks found within it. This article talks about the Appalachians being ~400 million years old and the rockies being ~180 million years old, however the rocks within the Rockies are the same age or older than the St. Francois rocks,the Appalachian crust is also that old. Thats because pre-existing crust can be uplifted to form mountain ranges. Some mountain building events can intrude new rock into pre-existing rock, the new rock is not the age of the crustal block into which the new magma is being intruded. This can occur in rift zones (extension), volcanic hotspots (yellowstone) and on-continent volcanic arcs (Andes, Mexico). Virtually every square inch of continental crust was once in a mountain range, due to the way that continental crust forms. Mountains are uplifted, than worn away into a flat plain eventually. In the Appallachians, even though mountains ranges have existed there 450 million years ago, they are not the same mountains, many Appallachian eras were eroded flat only to be re-uplifted later on. The re-uplifted mountains are not the same rock that the older mountains were, the new mountains would be rock that were located below the rocks of the older range that was eroded away. What this means is that the age of the rock in St. Francois is not necessarily the age of the uplift. I would probably say that the St Francois has been re-uplifted. I have heard that St Francois has long been an area of high relief (whether or not mountains) and some who theorize that the mountains have never had a marine transgression over the past 500 million years (the first sediment recorded marine transgression in MO was 500 million years ago with the formation of the basal sedimentary unit in MO, the Lamotte Sandstone). The absense of a sedimentary layer is not itself a gaurantee there has never been a marine transgression, however previous sedimentary formations may have been eroded away or have been transformed through high grade metamorphosis. Crust under Missouri was, we can be 100% certain once covered with sea early in the crustal formation, as most continental crust is formed as oceanic crust then heavily intruded by island arc subduction related magmatic processes, the primary means by which continental crust is generated from oceanic crust. A land surface would have first appeared on the crustal blocks during the island arc phase, and further during the accretion phase onto the continental margin. As time passes, the mountains are worn away and can become a flat plain and eventually transgressed by the sea where sedimentary layers can be deposited. An area nearby a margin can be reuplifted again due to collisions of new island arcs and continents to the margin. Areas in the interior of a continent can be reuplifted due to hot spot activity, intracrustal pressures transmitted through the crust from faraway tectonic zones, horst graben extension, rifting, as with the Laramide orogeny, direct tectonic effects due to shallow subduction, or may simply be a highland for long periods of time due to being relatively thick and/or light due to isostatic equilibrium, and a combination of these. One theory as to the modern Appalachians is that they have been uplifted due to intracrustal pressures and isostatic balance is due to pressure from the Laramide orogeny transmitted intracrustally. The St. Francois shares some similarities with the Llano uplift, these places may have thicker crust and maybe more felsic crustal content which causes them to stick up farther than other places. There can also be difficulty in distinguishing between an uplift and a simple arch, an arch can be the result of variable subsidence, areas outside of the arch may subside faster under sediment loading , the arch can appear to be an uplift when in fact its not because the areas around it have sunk more. This may due to isostatic qualities of the crust being more favourable due to depression in some areas rather than others. Millueradfa ( talk) 16:12, 24 May 2015 (UTC)
P.S. It is debatable as to whether the current St Francois Mountains could be 1.3 billion years old any more so than the the rockies and or appalachians, because it is unlikely that there has been no erosion and re-uplift of the St Francois in the past 1.3 billion years. The rocks are much, much older than the current uplift. Millueradfa ( talk) 18:46, 25 May 2015 (UTC)
