White River Ash re Dene/Dineh

[edit]

I didn't know how or where to insert this; maybe in the opening paragraph concerning the White River Ash; see this article in UpHere magazine, from Yellowknife, concerning one archaeologist's theory about why the Dineh (Navajo) moved south from what appears to have been their former domicile in the Nahanni area....(note the name similarity)....figured it's more than signficant enough to include here and in teh White River Ash article.....Skookum1 (talk) 23:57, 29 October 2008 (UTC)[reply]

The clicked map does not show location

[edit]

We can see the location on the map, but if we click the map, there is no longer a location indicator. Tallard (talk) 17:21, 16 April 2023 (UTC)[reply]

Legends

[edit]

While this source draws a link between a volcano in the White River region and legends of volcanic activity, the primary source does not seem to refer to the White River region. Jo-Jo Eumerus (talk) 14:10, 7 January 2024 (UTC)[reply]

Possibly outdated study

[edit]

Parking this source here b/c from the later sources it seems like there is stronger support for a link between the Dene migration and the 2nd White River Ash. Jo-Jo Eumerus (talk) 16:28, 7 January 2024 (UTC)[reply]

Also, this probably needs careful writing: A Multiscalar Consideration of the Athabascan Migration does argue that the Athabaskan migration was due to demographic shifts, but Power, security, and exchange: Impacts of a Late Holocene volcanic eruption in Subarctic North America says that evidence for a volcanic forcing is still good. From reading other recent sources, it seems like there is a consensus that the volcano "probably"/"may" have played a role in the Athabaskan migration, so leaving the article unchanged for now.

    No edit wars, etc.:
  6. It is illustrated by images and other media, where possible and appropriate.
    a (images are tagged and non-free content have non-free use rationales): b (appropriate use with suitable captions):
  7. Overall:
    Pass/Fail:
  • I randomly googled three phrases and only turned up Wikipedia mirrors. Earwig's tool shows no sign of copyright violation (the main things flagged by Earwig are the titles of the sources and phrases such as "White River Ash eruptions" or "1991 eruption of Mount Pinatubo" which are rather difficult to phrase otherwise).
  • References:
  • Spotchecks:
    • "It is the tenth-highest peak in the United States.." is sourced to this source p. 18 which supports the information
    • "The age of the Churchill-Bona massif is unknown" is sourced to this source p. 113 which supports the information
    • "The eastern White River Ash has a colour ranging from white to beige" is sourced to this source p. 242 which supports the information
  • General:
    • There are a LOT of duplicated links here - examples - Pumice is linked three times in the second paragraph of Geography, tephra twice in the same paragraph, Pacific Plate twice in the third paragraph of Geology, etc.
  • Lead:
    • "Churchill and its higher neighbor Mount Bona about 2 mi (3 km) to the southwest are both ice-covered volcanoes; Bona is the highest volcano in the United States" why are we giving prominence to Bona here? Suggest "Churchill and its neighbor Mount Bona are both ice-covered volcanoes with Churchill having a 2.7 by 4.2 kilometres wide caldera just east of its summit."
    • This is in Alaska, right? So ... why is kilometres used? Even if we use metric because of the scientific aspect, shouldn't it be "kilometers"?
  • Geography:
    • "The mountain is in the University Mountains sub-range[1] of St. Elias Mountains of Alaska" suggest "Mount Churchill is in the University Mountains sub-range[1] of the St. Elias Mountains of Alaska"
    • "Mount Churchill is a 4,744 metres (15,564 ft),[8] 4,766 metres (15,636 ft),[2][10] 4,767 metres (15,640 ft)[6] or 4,768 metres (15,643 ft) high[a] peak" is very clunky - suggest "Various measurements have placed Mount Churchill at 4,744 metres (15,564 ft),[8] 4,766 metres (15,636 ft),[2][10] 4,767 metres (15,640 ft)[6] or 4,768 metres (15,643 ft)." and split the rest of the original sentence into another sentence. Also - why "metres" for an Alaskan subject? Shouldn't it be either feet or "meters"?
    • "amphitheatre" again - why British English spellings for an Alaskan subject?
    • "coloured/colored" again - why British English?
    • "A 90 metres (300 ft) high pumice mound on the other side of the glacier, 16 kilometres (9.9 mi) from Mount Churchill, was formed by tephra building up on a bedrock bench; was once considered the vent of the White River Ash." is very complex - suggest "A 90 metres (300 ft) high pumice mound on the other side of the glacier, 16 kilometres (9.9 mi) from Mount Churchill, was formed by tephra building up on a bedrock bench. This mound was once considered the vent of the White River Ash flows."
  • Geology:
    • "Unlike other volcanic arcs, the Wrangell volcanic field features numerous large shield volcanoes, which are among the largest volcanoes in volcanic arcs on Earth." I'm not sure what the "unlike other volcanic arcs" is exactly trying to get across. Nor does the "which are among the largest volcanoes in volcanic arcs on Earth" supposed to tell us either.
    • "The basement under Mount Bona is formed by a plateau consisting of Permian to Pennsylvanian-age rocks[49] and Tertiary granites; most of Mount Bona may be formed by these nonvolcanic rocks." the relevance of this to Churchill is unclear.
    • "Volcanic rocks are dacitic[e] and define a calc-alkaline[56] adakite suite" is this ALL volcanic rocks or just the rocks at Churchill?
  • Ice cores:
    • "An ice core taken in 2002 from the col between Mount Churchill and Mount Bona[72] is the longest non-polar ice core as of 2006,[73] being 460.96 metres (1,512.3 ft) long." I suggest removing this - as it's (1) trivia and (2) likely outdated trivia. Combine the remaining sentence with the following paragraph.
  • Eruption history:
  • White River Ash eruptions:
    • the first paragraph is a bit confusing - we date one eruption as "1890" years ago but date the other as occurring in 852/853. Then we say they "occurred within a few centuries from each other." - I make the first erruption about 130 AD and the second in 852 - that's ... 700 years apart? A bit more than "a few centuries" and I'm not sure why we don't standardize on either 1890 and 1171 or 130 and 852? Also - suggest that we note that the first eruption is called the "Northern White River Ash" later and that the second is called the "Eastern White River Ash" later
    • "Only in 1984 and 1995 was the correct location, Mount Churchill, identified" suggest "Only in 1984 and 1995 was Mount Churchill identified as the source." since it's always possible that this will get switched in the future.
    • "It forms conspicuous layers along the Alaska Highway,[103] in riverbanks[107] of the Yukon, Tanana and their tributaries, which are often exploited by ground squirrels who dig their burrows into the ash." I'd ditch the bit about ground squirrels as it's a distraction and not very useful here.
    • "The ashes affect the properties of the soil they are in; ash layers can sometimes be the detachment surface of landslides." the second phrase of this sentence is awkward - perhaps "The ash layers affect the properties of the soil they are in; sometimes they are the detachment surface of landslides."
    • "Stumps of trees killed by the fallout emerge from the ash layers, close to Mount Churchill." why the comma?
    • "Given that tephra is not expected to cause fatalities in pre-modern peoples" but it is expected to cause fatalities in modern peoples???
  • Eastern White River Ash:
I've put the article on hold for seven days to allow folks to address the issues I've brought up. Feel free to contact me on my talk page, or here with any concerns, and let me know one of those places when the issues have been addressed. If I may suggest that you strike out, check mark, or otherwise mark the items I've detailed, that will make it possible for me to see what's been addressed, and you can keep track of what's been done and what still needs to be worked on. Ealdgyth (talk) 15:57, 6 February 2024 (UTC)[reply]
@Ealdgyth: Responded to a few queries and handled the rest. Jo-Jo Eumerus (talk) 16:52, 6 February 2024 (UTC)[reply]
Struck what's done and have inline replies for you to consider. Ealdgyth (talk) 14:53, 7 February 2024 (UTC)[reply]
@Ealdgyth: Did the rest. I wonder if you have access to any books about Athapaskan prehistory; one thing I have been wondering when writing this is how definitive the link between the eastern lobe and the Athapaskan migration is. Jo-Jo Eumerus (talk) 07:59, 8 February 2024 (UTC)[reply]
Changes look good. Unfortunately, I don't have any thing on pre-Columbian American history (or not anything that would shed light on your question) beyond what's in TWL. Passing this now. Ealdgyth (talk) 16:56, 8 February 2024 (UTC)[reply]

Did you know nomination

[edit]
The following is an archived discussion of the DYK nomination of the article below. Please do not modify this page. Subsequent comments should be made on the appropriate discussion page (such as this nomination's talk page, the article's talk page or Wikipedia talk:Did you know), unless there is consensus to re-open the discussion at this page. No further edits should be made to this page.

The result was: promoted by Lightburst talk 16:18, 20 February 2024 (UTC)[reply]

Improved to Good Article status by Jo-Jo Eumerus (talk). Self-nominated at 07:33, 9 February 2024 (UTC). Post-promotion hook changes for this nom will be logged at Template talk:Did you know nominations/Mount Churchill; consider watching this nomination, if it is successful, until the hook appears on the Main Page.[reply]

  • Which of your DYK-reviews is QPQ for this one?
  • The hook is very interesting, but doesn't it need a "that" in front of "Mount Churchill" (or, alternatively, "the volcano Mount Churchill"? Also, I suggest "caused" instead of "driven".
  • The hook statement does not seem to be clearly stated in the article. The article only states that a migration happened between the eruption and the arrival of Europeans, but it is not clearly stated (and sourced) that the volcano might have been responsible for this long-distance migration.
  • Unrelated to this, I suggest to add the elevation of the volcano to the lead. This is the first thing that many readers want to know when reading about a mountain.
  • Something on flora and fauna would have been nice, but optional for GA and DYK of course.
  • In conclusion: This is a recent GA; well written with high-quality sources, and comprehensive. No copyvio apparent. Only one image unfortunately, but it is freely licensed. --Jens Lallensack (talk) 02:53, 10 February 2024 (UTC)[reply]
Put the QPQ in (the "reviewed" parameter is for the QPQ not the reviewer); for want of time I usually don't do my QPQs immediately after the article work. Other Dene people migrated south and east[l] after the eruption is the text in question and many sources associate the Dene migration with the eruption. There is no information on flora and fauna, probably because the high St. Elias Mountains are well above the vegetation line. There are four elevation estimates and no clear way by which to prioritize. Jo-Jo Eumerus (talk) 07:58, 10 February 2024 (UTC)[reply]
Ok. But I still have two open questions: 1) You state that "Other Dene people migrated south and east[l] after the eruption" is the text in question, but this does not explicitly state that the eruption is responsible (no causality implied), which is the key claim of your hook. 2) If there are several elevation estimates and it is not clear which is to prioritize, why is only one given in the infobox? In that case, all four should appear in the infobox (or none, or a range), but picking only one of those estimates seems arbitrary to me. Jens Lallensack (talk) 13:29, 10 February 2024 (UTC)[reply]
Pulled the infobox claim. For the other, it's in an entire paragraph about how people migrated because of the eruption. Jo-Jo Eumerus (talk) 08:40, 12 February 2024 (UTC)[reply]
OK. Passing now, nice work! Jens Lallensack (talk) 11:10, 12 February 2024 (UTC)[reply]
