Talk:Mount Rainier

Name of Mt. Rainier

I realize I was wrong to unilaterally change the opening sentence to exclude “also known as Tacoma or Tahoma.” I am not going to do that anymore. I am genuinely trying to reach a consensus. I live in Eatonville Washington near Mt. Rainier and nobody calls it Tahoma/Tacoma. The official name is Mt. Rainier. I was wondering if the native name could be in the info box but in the lead sentence it could just say “Mt. Rainier.” I will abide by whatever is reached through consensus. I’m just offering a suggestion. NapoleonX (talk) 05:21, 9 May 2021 (UTC)

Parent peak of mt. rainier in Mexico ???

This is insane 2600:6C4E:B7F:F850:F84E:C532:603A:9555 (talk) 04:03, 11 July 2022 (UTC)

The source explains: The prominence parent for a peak is the nearest ridgewalk-connected higher peak with greater prominence than the given peak. It will always be both higher and more prominent than the peak itself. Schazjmd (talk) 13:43, 11 July 2022 (UTC)

Native Names of Rainier

Per MOS:LEADLANG, only one non-English name for a place can be in the lead sentence if that name is a common variant. Otherwise, other names must be elsewhere in the article. TaivoLinguist (Taivo) (talk) 06:02, 28 January 2023 (UTC)

"Tahoma" certainly qualifies, as it has fairly wide use in geographic names (Little Tahoma, Tahoma National Cemetery, Tahoma State Forest, Tahoma School District, etc.) and has been used as a substitute or second mention for Rainier by non-local outlets, such as the LA Times and the Washington Post. SounderBruce 06:08, 28 January 2023 (UTC)

Tahoma is an English name, təqʷubəʔ is a non-English name. Like @SounderBruce said, Tahoma is a common secondary English usage word for the mountain, so, in my opinion, both should remain. PersusjCP (talk) 06:12, 28 January 2023 (UTC)

Yes, since its a common name in English, "Tahoma" certainly qualifies under MOS:LEADLANG as an alternate, but not the Lushootseed original. The Lushootseed original can be in the "Name" section and is certainly appropriate there. --TaivoLinguist (Taivo) (talk) 06:20, 28 January 2023 (UTC)

Is this a reliable source?

Can I trust this article? For school research? Because no one at my school believes Wikipedia is a reliable source. Foofy Plop (talk) 15:39, 10 May 2023 (UTC)

@Foofy Plop, the reliable sources are listed in the References section at the bottom of the article. Schazjmd (talk) 15:40, 10 May 2023 (UTC)

Tahoma

Mount Rainier isn't called Tahoma. It's near Tahoma though. Right? Foofy Plop (talk) 17:39, 11 May 2023 (UTC)

Tahoma is another name for the mountain. There is no "place" named Tahoma. Schazjmd (talk) 17:51, 11 May 2023 (UTC)

Last eruption

The infobox listed the last eruption as 1450, but the text of the article lists recorded 19th century activity. This is a contradiction in the article, and the way we normally handle it is by noting both sources since both are reliable. I've moved the 1450 date and citation to the body of the paragraph and out of the infobox so not as to overweight it. Happy to discuss, but came across this as a reader and it was fairly confusing, so I went ahead and made the change. If people think there's a better way to address it, I'm all ears. Just don't think the status quo is the right presentation. TonyBallioni (talk) 03:51, 24 July 2023 (UTC)

Elevation

The elevation was changed in this article on Sept. 9 2024, but is not based on an official measurement. I'd propose that elevations of mountains in the United States should use the USGS as the official measurement. Additional measurements could be added, but should not replace the USGS measurement until any new measurements are adopted by the USGS. 2601:601:602:50A0:5272:B05:CE0:FBB5 (talk) 17:36, 11 September 2024 (UTC)

I agree, these findings were published in a blog post and not even peer reviewed. ☆ Bri (talk) 15:35, 6 October 2024 (UTC)

The blog post even says "[Note these results are not official unless approved by Rainier National Park]". The edit should be reverted. DJ Cane _(he/him) (Talk) 14:48, 7 October 2024 (UTC)

Odd that he would say that the National Park Service determines elevation, I would think it is actually a function of US Geological Survey (USGS). Don't infoboxes always use USGS heights? ☆ Bri (talk) 22:44, 7 October 2024 (UTC)

You're correct, I'm just pointing out that even the source offered says they shouldn't be used as the official elevation. DJ Cane _(he/him) (Talk) 17:06, 8 October 2024 (UTC)

I just added the 2024 survey elevation back into the infobox, but below the official elevation with notes explaining both heights. KnowledgeIsPower9281 (talk) 11:42, 13 October 2024 (UTC)

Having two elevations listed is confusing to the general reader and in my opinion having one guy who formerly worked for the Signal Corps back up the claim doesn't add much validity to it. Peer review typically involves replication of the hypothesis by multiple subject matter experts followed by publication in an academic journal. I'm not sure why the rush to get this number out matters beyond padding Gilbertson's resume, NOAA and USGS are currently involved with developing a new datum for use within the entire United States. I think we should wait to change elevation numbers in the infobox until that project is finished in the next couple years. DJ Cane _(he/him) (Talk) 14:17, 13 October 2024 (UTC)

@KnowledgeIsPower9281:, your attempt at footnotes didn't work; I've fixed them, but in the future, please check that what you do to an article displays properly. Although I fixed the edit, I agree with DJ Cane. Schazjmd (talk) 14:31, 13 October 2024 (UTC)

Then maybe the best thing to do would be to keep a footnote on the official elevation, but mention Gilbertson's survey elevation in the footnote since the official elevation is likely outdated information at this point. Columbia Crest is most likely no longer the highest point of the volcano, with the Southwest Rim now being the probable highest point. This information pertains to climbers who want to reach the current highest elevation of the volcano, even if the survey is unofficial. I do agree that the official one should be kept until the new findings become official. KnowledgeIsPower9281 (talk) 16:19, 13 October 2024 (UTC)

I think a footnote mentioning Gilbertson's survey is an appropriate compromise though I don't think it needs to be particularly detailed. The body of the article is the appropriate location for details.

I suspect the survey does bring up important changes on the volcano. I don't question the need for updated data nor do I think the survey is wildly inaccurate (which is why I didn't remove it wholesale in my edits), we just need to make sure we are using the best data in line with community standards for what we consider to be reliable sources which includes not giving undue weight to unofficial sources. DJ Cane _(he/him) (Talk) 17:06, 13 October 2024 (UTC)

@SounderBruce: it looks like you added a citation, and may not be aware of this discussion. Do you have thoughts one way or the other? ☆ Bri (talk) 21:18, 8 October 2024 (UTC)

• Comment: The following comment was left on this talk page in a new section. I am adding it here so that participating editors get notified.

Hello everyone, I'm the Park Geologist at Mount Rainier. Someone recently changed the height of the mountain on the wiki entry from 14,410 (official height) to 14,399.6 (a single survey done by Eric Gilbertson that is not peer reviewed or official in any way). Can we get that changed back to 14,410 for now until we have a chance to review Eric's work, his raw data, and have NOAA's Geodetic Survey weigh in on the official height? Again, the work by Gilbertson is NOT official and should to be represented as official until we all can weigh in on it. Thanks! - Scott Beason (scott_beason - at - nps.gov)

DJ Cane _(he/him) (Talk) 20:59, 9 October 2024 (UTC)

• Update: As there has been no dissent and this has been open for several days now, I have reverted the infobox elevation and citation back to the old value. I have also removed the Height subsection and moved relevant portions of the prose into the Subsidiary peaks subsection. I kept the new data as it appears to have some weight, but reworded it to show that it is new research that isn't official or peer reviewed. I kept existing citations for that section.
  • The revert seems to have also undone a number of useful edits made after the height change and need to be patched back in. I do think that mentioning the new height data is worth doing so in the text just to prevent further edit warring and arguments. SounderBruce 03:25, 17 October 2024 (UTC)

  • Adding new height data from a blog with nothing else to verify it just to end this argument doesn't seem worth it to me. Until and unless the data is verified, I'm against the new data. Also, WP:BLOGS is against the new data since it is from a blog. Hacked (Talk|Contribs) 03:44, 17 October 2024 (UTC)

Clarification on Elevation

Eric Gilbertson here. I did the recent Rainier surveys and I’ve heard there’s been some misinformation floating around on Wikipedia about this. I wanted to clear up any confusion. I usually trust Wikipedia as a source of factual, unbiased information, but this article appears to fall short of that standard.

-As Scott Beason mentioned, the park is currently reviewing my measurements and is still keeping its long-standing value of 14,410ft currently. This was the number from the 1956 USGS survey.

- My 2024 measurements were based on multiple ground surveys conducted in August and September of this year and corroborated with independent Lidar surveys from 2007 and 2022. Lidar data for Rainier is publicly available at https://lidarportal.dnr.wa.gov/ and can be analyzed by anyone using QGIS, a free software package that can be downloaded at qgis.org

-My methodology and measurements were peer-reviewed by Larry Signani and he says the results are sound and confirm the melting of Columbia Crest (see Seattle Times article interview with Larry Signani found here: https://www.seattletimes.com/seattle-news/climate-lab/mount-rainier-is-shrinking-and-now-has-a-new-summit/)

-The number currently used on wikipedia, 14,411ft, was also determined by Larry Signani as part of the earlier surveys. He was the geodesist from the Land Surveyors Association of Washington (LSAW) Rainier surveys of 1988, 1998, and 2010. You will find his name as the author of the second article currently cited on Wikipedia for the 14,411ft number (“The Height of Accuracy” Point of Beginning). I will note it is a double standard to cite his result from those years but not from 2024.

-The other source currently cited for the 14,411ft elevation is from The News Tribune. This same newspaper has now recognized the height of Rainier as that of my measurement, 14,399.6ft. See https://www.thenewstribune.com/news/local/article293659974.html

-Peakbagger uses the 2024 measurement of Rainier, 14,399.6ft (NGVD29). (https://www.peakbagger.com/peak.aspx?pid=2296) Peakbagger is the most trusted source of peak elevations around the world. Wikipedia cites peakbagger for the 14,411ft number, but Peakbagger actually uses 14,399.6ft (rounded to 14,400ft to the nearest ft).

Thus three of the four sources Wikipedia is currently citing for the elevation of Rainier (Larry Signani, The News Tribune, Peakbagger) are now actually using the value I measured (14,399.6ft). The fourth source, opentopomap.org, is listing 4392m, which is 14,409.45 ft and not even consistent with the 14,411ft number currently listed on Wikipedia.

-Wikipedia should be careful which datum it is using. The 14,411ft number is NGVD29, not NAVD88 as is currently written on Wikipedia. The NAVD88 number for that survey was 14,417ft. The park number 14,410ft is in NGVD29, so I recommend using that datum for all elevations on this page to be consistent with the park.

-Rainier National Park never formally recognized the 1988, 1998, or 2010 LSAW surveys of Rainier (14,411.1ft, 14,411.0ft, and 14,411.0ft respectively) and has always kept the number from the 1956 USGS survey (14,410ft). Surveyors and mountaineers in Washington use the LSAW results, though.

-I recommend, if Wikipedia wants to get this article as accurate as possible, that it first mentions the officially-recognized park height of 14,410ft. Then it should also mention the numbers from the 1988, 1998, 2010, and 2024 ground surveys. This way readers will be aware of the most recent ground measurements and also aware of what is recognized by the park. Wikipedia should also be explicit and accurate about which datum it is using. This might not be a big deal on the east coast of the US (where the datums are only different by a few inches), but on Rainier they are different by around 6ft. Eric Gilbertson (talk) 23:56, 16 October 2024 (UTC)

Peakbagger seems bloggy and shouldn't be used as it's bloated with Amazon affiliate links, data based on user submissions and such. The data should be referenced to whatever values used in reliable geology related books from reliable publishers (Authorhouse for example doesn't count as such) and websites like countryhighpoints.com have no business being cited anywhere on entire Wikipedia. Graywalls (talk) 00:10, 17 October 2024 (UTC)

Wikipedia:Reliable_sources/Noticeboard/Archive_362#Is_Peakbagger.com_a_reliable_source? There's discussion there about Peakbagger and there's no definitive consensus. Some information maybe reliable, but at its core, hard data seems to be crowdsourced and the data accuracy is at the mercy of the contributor. The GPS reading could have been taken by a child sitting on his dad's shoulder and that would throw it off by 5-6'. Database based on publicly submitted data can not be trusted as a source for encyclopedia writing. Graywalls (talk) 00:18, 17 October 2024 (UTC)

I have clearly described my measurement methodology in my report that can be found in the link below. Please do not misrepresent the methodology of the 2024 measurements.

https://www.countryhighpoints.com/mt-rainier-elevation-survey/

The measurements and methodology have been peer reviewed by the leading experts in the field of measuring the height of Rainier. See previous citations of source. I have also provided my raw measurement RINEX files in the measurements section of my report linked above. Any surveyor can process them and see for themselves.

Peakbagger editorial staff is composed of experts in the field. Results are reviewed by staff before being published on the site.

I welcome fact-based scientific discussion on the points I have brought up in my message above. If you do not dispute any of these facts, then I encourage other Wikipedia editors to weigh in. Then I encourage wikipedia to adopt these changes to make the article factually correct and unbiased.

I would like to remind you of Wikipedia's "argument from authority page", which states "Scientific knowledge is best established by evidence and experiment rather than argued through authority"

See here:

https://en.wikipedia.org/wiki/Argument_from_authority#Use_in_science Eric Gilbertson (talk) 04:31, 17 October 2024 (UTC)

@Eric Gilbertson:, that discussion (about peakblogger) should take place on RSN. Start a new discussion. Even if the provided data was "reviewed", it is based on user-submitted value. As of last discussion, there was no consensus that it's a reliable source. Graywalls (talk) 04:57, 17 October 2024 (UTC)

Topographical prominence

Where did the information in peakbagger.com come from? I see it there, but I don't know how it came about. Graywalls (talk) 02:53, 17 October 2024 (UTC)

@SounderBruce: about Special:Diff/1251625417, this wasn't so much a deletion, but I was able to substitute the National Geographic Source you located for the info. Minus the trivia like "ultra promient". I believe National Geographic should be used, rather than peakbagger.com for this. Graywalls (talk) 03:20, 17 October 2024 (UTC)

Regardless of which source is preferred, it is not appropriate to edit war. SounderBruce 03:22, 17 October 2024 (UTC)

I'm working on it right now. Instead of going back and forth, please check in about an hour. Graywalls (talk) 03:28, 17 October 2024 (UTC)

Final Consensus

After the discussions over the past few days, what is the general Wikipedia consensus on Rainier's elevation? I believe that the current revision of the page should not be the final outcome of this discussion as it is incorrect and outdated. I also added a banner to the top of the page indicating this subject is currently being heavily edited and discussed. KnowledgeIsPower9281 (talk) 12:18, 17 October 2024 (UTC)
