message: Here's some additional info that can help clear up some of the discussion.. Also, I have just come back from this location, so if you have any questions, let me know and I can probably add more color:
"Although both the Nunavut Act and the Nunavut Land Claims Agreement state the intersection of 60°00'N latitude and 102°00'W longitude as the boundary between Manitoba, Saskatchewan, and the Northwest Territories, the actual, legal boundary point is marked by a survey monument boundary marker placed by the Manitoba Saskatchewan Boundary Commission in 1962.[27] According to Natural Resources Canada, Geodetic Survey Division, that monument's precise location is 59°59′57.98511″N 102°0′27.24027″W (NAD83), or about 400 metres (1,300 ft) west and slightly south of 60°N by 102°W."  — Preceding unsigned comment added by 166.84.160.135 (talk) 08:26, 28 July 2012 (UTC)

thread_title:  More info 

message: Whether there is an exact quadripoint or a surveying error was discussed above. However, as someone suggested, the Manitoba Saskatchewan border maybe is not meant to be at exactly 102°W. I am finding quite a few sources saying exactly this. Geography of Saskatchewan#Physical geography says so without a reference I can make sense of. This and this hint at it, this shows it (you'll have to zoom in) and this says it. None of these references is fully satisfactory but I'll keep looking. Even if the "four corners" is not exact (but out by a few hundred metres) the article is still worth having and the anomaly worth discussing if it can be done with reference to reliable sources, Thincat (talk) 00:17, 14 May 2013 (UTC)
replies: text: The error between the survey practices back then compared to what we now use for latitude (the international border isn't exactly 49°) and longitude is a well known fact, and common knowledge in the surveying world. I know this is OR, but all you have to do is drive to the nearest meridian (Range Road 10), and look at your GPS. 117Avenue (talk) 03:52, 14 May 2013 (UTC)
replies: text: The border is as surveyed, and enabling legislation prescribing a meridian is only a guideline (haven't seen a quote of the MB-SK border description or an NT-NU border description).  AS with the BC borders with WA and AK, the actual physical lines and surveyed monuments do not match with the 49th Parallel in the one case, or any fixed "line" though the peak-to-peak survey in the latter case was where those specific points are; what I'm saying is that it's not the theoretical line that's the boundary, but the boundary as surveyed.  Which is why there's a hundred yards or so of WA that should be in BC in the Lower Mainland area; divergence easts of the Rockies means the Americans came out better in total acreage "gained".....this so-called "quadripoint" is fictional, as is the name and subject of this article, which IMO should be deleted as "original research" which it most definitely is, in many ways.Skookum1 (talk) 04:16, 14 May 2013 (UTC)
thread_title:  Manitoba Saskatchewan border 

message: This image shows 1959 and 7 years in jail. I  emailed the lodge to see if they can send us an image of the top of the marker. I assume the 59 was stamped in at time of placement so 1962 and five years in jail would be wrong in the article. 1962 may have been the estimated completion time of the project and they had all the obelisks stamped with that.--Canoe1967 (talk) 11:30, 20 May 2013 (UTC)
replies: text: What an interesting photo. The "five years" comes from a rather bloggy source (and I guess it could be wrong) but it claims to quote exactly what is inscribed on the obelisk itself including "1962" and the photo of the obelisk confirms 1962. The article strictly does not say the obelisk was erected in 1962 but says it is "inscribed to say it was erected in 1962". I remember writing that bit, knowing that pedants would be scrutinising every key press for OR. The new photo you have uploaded indicates Manitoba on one side and NWT on the other (which by my OR suggests Nunavut now). I think the legend could be re-written "A 1959 survey marker indicating the boundary of Manitoba and Northwest Territories near Hasbala Lake." Thincat (talk) 19:53, 20 May 2013 (UTC)
replies: text: I just added 5 more images to the commons category. There are two markers close to each other and both are in the article now. When the photographer goes to the obelisk again he may send us a picture of the top of it.--Canoe1967 (talk) 21:53, 20 May 2013 (UTC)
thread_title:  Date and years 

message: I would be happy to rename the article "four corners" or "Four corners" (including the quotes in the title) since that seems to be the common name, probably with (Canada) appended to disambiguate from Four Corners. My reasoning is that that is what the several sources seem to call the place.
In many ways I'd be happier if the lead, instead of saying "where four political subdivisions hypothetically meet" said "where four political subdivisions come close together or meet" except no-one seems to have found a source saying anything like that. The sources seem to say (possibly wrongly) that the boundaries cross. The article should not be (and isn't) claiming a precise quadripoint (or that it is not one). Do we know if this particular location on the NU-NWT boundary has been surveyed yet? If not, and from what I understand from earlier discussion the 102° is something of a guideline, until the surveyors have reported we cannot know the situation. If this part of the survey is complete, it is a great pity none of us seem to know the result. Of course, piecing together the various evidence seems to show no exact crossing but without a reliable source reaching that conclusion, we may not claim it in the article.
Finally I have just noticed that, back in 2009, material was copied from here to quadripoint hence the admonition near the top of this talk page. Thincat (talk) 21:30, 20 May 2013 (UTC)
replies: text: As far as I can tell via googling, the NWT-NU boundary surveys so far have concentrated on areas near settlements and those near mineral claims. Pfly (talk) 10:13, 21 May 2013 (UTC)
replies: text: Must not be very much surveyed then.......well, the diamond claims get pretty extensive I guess......no diamonds near the 60th Parallel and the SK/MB boundary yet, but if it comes down to NT/NU/SK/MB squabbling over whose jurisdiction gets royalties, it'll get surveyed and darned fast LOL.Skookum1 (talk) 02:25, 22 May 2013 (UTC)

text: I am okay with "four corners" with quotes and no caps. Are we sure that we didn't create the label though? Some RS use this term but may have taken it from us. We could still join the four surveyor forums that I brought up in the AfD. We could let them neverendum it and then get back to us. They would be the world experts on it I assume. They may have valuable input to improve the article as well.--Canoe1967 (talk) 06:24, 22 May 2013 (UTC)
replies: text: The title should be Four corners (Canada), without quotes. Four Corners is not the proper name for this place, so we should use a descriptive name. There are four corners (whether they all meet at the same point or not...), so it is an accurate description, and it reflects the obvious parallel with the Four Corners in the US (which is a proper name). Per WP:TITLEFORMAT we should not use quotes or a capital C, but the initial F should be a capital. Bazonka (talk) 21:28, 22 May 2013 (UTC)
replies: text: Makes sense to me too. Pfly (talk) 22:57, 22 May 2013 (UTC)

text: Having started this bit of the discussion I forgot all about it but I am happy with the result. It hadn't actually occurred to me that there are four corners whether or not they all come together! As for the initial capital letter that is WP's way of doing titles except under highly unusual circumstances. I think the geometrical uncertainty adds to the interest but that is a matter strictly for the talk page. Thincat (talk) 19:56, 12 June 2013 (UTC)

message: I made :File:Geodatata for Sask Man NWT and Nan.png and pixel counting in GIMP works out to 386.5m. Do we have an accurate number for what it should be?--Canoe1967 (talk) 21:53, 24 May 2013 (UTC)
replies: text: That's close to the "about 400 m" I calculated some years back. I got that number by dropping the two coordinates (60°00'N 102°00'W and 59°59′57.98511″N 102°00′27.24027″W) into some online distance calculator, perhaps the measure tool in Google Earth. Your map is interesting, but I'm not sure about its ultimate accuracy. It comes from OpenStreetMap, yes? OSM is a Wikipedia-like source, in which anyone can make edits. I haven't used it in a long time but have an editing account, so I went in and tried to determine who entered those boundaries and what their source was. I'm not very good with OSM, but it seems that all the boundaries in that area say their source is "geobase", meaning, I assume, GeoBase (geospatial data). As our article on GeoBase says, when it comes to geopolitical boundaries, "This data layer contains the international, inter-provincial, and territorial boundaries, as well as the boundaries of Canada’s exclusive economic zone. It is not intended for legal use, and should be utilized for cartographic purposes only." And, for what it's worth, neither of the coordinates on your OSM map are the same as those given by Natural Resources Canada, CSRS Online Database, station number 674002 (MON 157) (Established by : Legal Survey Of Canada - Nrcan), which I just checked again (register/login here ) and got the same coordinates already on our page here: N59° 59' 57.98511",  W102° 00' 27.24027" (NAD83). To convert between decimal and DMS coordinates I use , which for the survey monument gives 59.99944,-102.007567. Inputing the CSRS coordinate and 60.0N102.0W into  gives 424.9870362099465 m. All that said, "about 400 m" seems good to me! Pfly (talk) 04:44, 25 May 2013 (UTC)
replies: text: Also, for what it's worth, the high-res topo maps of Canada (NRCan made) appear to still be available online via "mytopo.com", this link  should show the MT-SK-NWT "tripoint" marked with a survey monument symbol and the number "157". There are no topo maps at this scale just to the east, including where the NU-NWT boundary is shown on smaller scale ("lower res") topo maps. I'm not sure why that is. The topo cutoff is marked "District of Mackenzie", a pre-Nunavut name whose boundary was along 102°00'W, although never surveyed on the ground. It seems the District of Mackenzie/Nunavut was never mapped with topo maps at this scale. Pfly (talk) 05:14, 25 May 2013 (UTC)
replies: text: If you go to the link I got the map image from there are more maps there that may help. That was the only CC-by one that we can license at commons though. My dad was a surveyor for highways. He said there should be a marker ever square mile in Canada. He may have only been talking about south of 60 though. Sites like http://www.waymarking.com/ seem to enjoy finding and posting pictures of them.--Canoe1967 (talk) 08:43, 25 May 2013 (UTC)
replies: text: Getting an exact distance is possible through converting the coordinates to UTM. The toolserver includes this function (, ). Simple Pythagorean theorem will tell you it is 427m.  Topo maps do exist east of 102°, the topoquest link, also found through the toolserver, has them. However can only show one side of 102° at a time, because of how the National Topographic System divides its map sheets. 117Avenue (talk) 00:06, 26 May 2013 (UTC)

text: Huh? Have you not read the article? An obelisk marks the point where the Manitoba–Saskatchewan border meets the Northwest Territories, at 59°59′57.98511″N 102°00′27.24027″W (NAD83), 427m west of 60°N 102°W. The Northwest Territories–Nunavut border is unmarked, and is either at 102°W or 102°00′27.24″W. 117Avenue (talk) 04:56, 28 May 2013 (UTC)
replies: text: I am just wondering where our 4 - 6 points are in relation to each other. We have legal borders that don't match 102/60, we have two markers that were placed, and we have true 102/60. I assume that the markers are at the legal border limits. Is the N/S marker precisely on 60 and where is it E/W? There should be a government account of where it was last found which may vary slightly from where they thought it was when it was placed. If we can find at least these two points then we should be able to create a diagram from the data. 102/60 we don't really need from OSM since it is simple trig. We just need to place our two markers as last found in relation to those two trig lines. This will give the readers some nice eye candy so they can actually 'see' where they are. Without the last surveyed locations of two more markers we shouldn't draw the legal borders in though.--Canoe1967 (talk) 16:27, 28 May 2013 (UTC)
replies: text: I don't understand what you mean by "we have two markers that were placed". There is the obelisk at N59° 59' 57.98511", W102° 00' 27.24027" (NAD83), placed before the creation of Nunavut and marking the tripoint of Manitoba, Saskatchewan, and NWT. What other marker is of concern? Pfly (talk) 22:57, 28 May 2013 (UTC)
replies: text: The N/S only one not far from it. See the image in the article?--Canoe1967 (talk) 23:05, 28 May 2013 (UTC)
replies: text: Considering you are the one who uploaded it, wouldn't you be the one to know? 117Avenue (talk) 04:54, 29 May 2013 (UTC)
replies: text: Canoe1967, do you mean the picture of the disc, "marking Manitoba's north border, east of the obelisk"? I'm not even sure why that picture is on this page. There are hundreds of survey markers along the provincial boundaries. Is that one special? I can get its coordinates from the CSRS Online Database if you'd like, although even if it is closer to 60°00'N 102°00'W I'm not sure how it would matter... Pfly (talk) 08:04, 29 May 2013 (UTC)

text: But, in case it does matter and I'm confused, the next survey marker along Manitoba's northern boundary, east of the tripoint obelisk, is, according to Natural Resources Canada, CSRS Online Database, station number 674004 (MON 1) (Established by : Legal Survey Of Canada - Nrcan), N59° 59' 58.01195",  W101° 59' 49.04294" (NAD83). Thus 179.895 metres from 60°00'N 102°00'W. So, closer to 60-102 than the tripoint obelisk. Maybe that is what you were getting at? If NRCan decides to use 60N,102W they will end up making a new tripoint located a bit closer to the disc marker than the obelisk (and slightly south of 60.0 N, presumably)—which would also mean there is no true quadripoint or "four corners". Of course if they decide to use the existing tripoint obelisk, making a true quadripoint, then the disc marker is irrelevent, right? Pfly (talk) 08:40, 29 May 2013 (UTC)

text: We should not change the F to lower case. The initial character of an article name should only be lower case in the special situations where the name always starts lower case - and this only really applies to companies and band names etc., for example k.d. lang and eBay. "Four corners" would have a capital F if it is used at the start of a sentence. Bazonka (talk) 16:44, 19 July 2013 (UTC)
