This article is about a volcano in northwestern British Columbia, Canada. I am nominating this for FA because it's a comprehensive account of this relatively obscure volcano. Hoodoo Mountain is one of the four volcanoes comprising the Stikine Subprovince which forms part of the Northern Cordilleran Volcanic Province in northwestern North America.

Support. I no longer Oppose moving this article to FA. All issues I have brought up have been resolved by the nominator. See my comments at the bottom of this section. Eewilson ( talk) 06:34, 17 October 2021 (UTC)
OLD - This article is too technical for the average reader to understand. The nominator has admitted such and has refused to simplify even the Lead. I do not have faith that those and related changes will be addressed and am stopping my review here (see the end of my comments) with an Oppose. Eewilson ( talk) 01:47, 13 October 2021 (UTC)
Hi! It looks like this had a good GA pass recently, so hopefully this review won't take too long. I'll see what I can find that has been missed.
Looks great. I think the lead is welcoming and will make the average reader want to go further now. I had already read the rest of the prose and found no issues with it, nor did I see any POV. I read and skimmed it just now and haven't changed my opinion on that. Thank you for your willingness to step back and take a look at the suggestions I made. I Support based on my review of technical, Lead, prose, and POV. Eewilson ( talk) 06:34, 17 October 2021 (UTC)
Nearly three weeks in and this nomination has garnered only one general support. Unless considerable further progress is made towards a consensus to support over the next three or four days I am afraid that this is liable to be archived. Gog the Mild ( talk) 19:14, 25 October 2021 (UTC)
What an interesting volcano! This is a very informative article, even for an advanced layperson. My only suggestion is to replace "phonolite and trachyte" in the lede with "highly silicic and alkaline igneous rock", but only in the lede. I can never remember the TAS diagram, and I imagine most other readers don't either. — hike395 ( talk) 06:48, 28 October 2021 (UTC)
Overall, I think this is a well-written and well-sourced article. Here are my detailed comments:
Geography
Biogeography
"Forests grow on the lower slopes of Hoodoo Mountain except for its northeastern flank where rock and ice are dominant. Much of this forest cover lies at elevations below 900 metres (3,000 feet)."
I suggest these two sentences should be moved/merged into the preceding paragraph which mentions the forests, rock, ice and valley bottoms.
Climate
"Hoodoo Mountain has a maritime glacial climate".
Is “maritime glacial climate” a recognized valid climate type? Or is it actually a maritime climate but glaciers also happen to be in the region (as a coincidence)?
Geology
Background
"Other volcanic formations, notably subglacial volcanoes, take their shape from ...". A subglacial volcano is a landform not a formation.
What is the relationship/hierarchy of Stikine subprovince and Iskut volcanic field?
Iskut Volcanic Field has 8 centres (Hoodoo Mountain being one of those centres), but it seems that of these 8 centres, only Hoodoo Mountain is a NCVP centre? Are the other 7 centres of Iskut not regarded as NCVP centres?
Stikine subprovince "consists of three other volcanic centres" should be changed to "includes three other volcanic centres" or "has three other volcanic centres".
I think it would be helpful to clarify the meaning of "volcanic centre" compared to "volcanic field".
Structure
"It has a basal diameter of around 6 kilometres (3.7 miles), a maximum volume of 17.3 cubic kilometres (4.2 cubic miles)" – what is the significance of "maximum"? Why not only "volume"?
"Hoodoos, needle-like rock formations after which the volcano is named" – I suggest that "spire" or "pillar" would be better than "needle-like".
"The lower set of cliffs delimit the base of the volcano except for its southeastern margin where they have been partially overrun by younger lava flows. They are 100 to 200 metres (330 to 660 feet) high and form a broad bench" – I think the "they" in "They are 100 to 200 metres ..." should be clarified – I think this refers to the cliffs not the younger lava flows?
"the glassy chemical composition of the lava" – glassy is not a chemical composition - "glassy chemical composition" should be changed to "glassy texture".
"The Southwest Flow is a large composite lava flow" - "composite lava flow” should be defined.
Volcanic history
"Some tephra layers in northern British Columbia may have been deposited by Hoodoo Mountain." Is this summarising the later paragraph about tephra at Dease Lake, Finlay River and Bob Quinn Lake? Without mentioning those locations in this summary paragraph, it reads oddly because Hoodoo Mountain is itself in northern British Columbia. I think it could be improved by adding a mention of how far away (in kilometres) from Hoodoo Mountain this tephra may have reached.
"Hoodoo has also been designated as a subglacial volcano due to much of the mountain having formed subglacially in the last 100,000 years." Did anything geologically or volcanically significant happen 100,000 to 85,000 years ago? If not, why mention 100,000 years? Elsewhere in the text, 85,000 years is mentioned: "The first eruptive period 85,000 years ago" and "The primary rock types comprising the volcano are phonolite and trachyte, which were deposited during six periods of eruptive activity beginning about 85,000 years ago".
Eruptive periods
Image of eruptive periods (File:Hoodoo Mountain eruptive periods.png): I suggest that ice is changed from blue (the traditional colour of liquid water in diagrams) to white (the traditional colour of ice in diagrams). Hoodoo Mountain is, after all, a subglacial volcano not submarine volcano.
"These volcanic deposits are mainly exposed on Hoodoo's southwestern and northwestern flanks": "Hoodoo’s" is too informal. I suggest it should be changed to "“Hoodoo Mountain's".
"devitrified glass with heterolithic clasts": Heterolithic should be defined.
"Lava flows on the north–central flank display radially-oriented cooling joints" – perhaps explain the significance of radial joints (as has been done with the horizontal joints in an earlier paragraph).
Tephra layers
I think it would be helpful to give some indication of the distances from Hoodoo Mountain to Dease Lake, Finlay River and Bob Quinn Lake.
Monitoring and volcanic hazards
These are geological subjects and should become a subsection of the Geology section.
Notes
Several terms are both wikilinked in the main text and defined in the Notes section. Why? Wikilinks (and/or very brief inline definitions in parentheses) are usually sufficient. Why are only these several terms and not every wikilinked word defined in the Notes section? I suggest these notes should be removed.
If the notes are kept, note 1 mentions "silicium" (which is copied from the cited source). In English, silicium seems to be an obsolete name for silicon (according to e.g. Collins English Dictionary). Perhaps the author/publisher of the source book forgot to translate the word from another language e.g. French or German, where it is the current correct term). "silicium" should be replaced by "silicon". I suppose the same cited source reference could be used but a better source using “silicon” can be found easily.

I feel like I'm expected to list things to change but honestly it seems fine to me as is. I'm not a geologist or volcanologist but understand everything better than I expected. There are a few terms I didn't know, but they are well linked, even with footnotes to give a quick overview of a jargony term (like aphanitic in the section Geology->Volcanic history->Eruptive periods—the term is linked but there's also a footnote providing a quick definition). And, frankly, I expect a page about a volcano and its geology to describe things using terms I'm not fully educated about. It strikes me as far less "difficult" to understand than, for example, Proteasome, Oxidative phosphorylation, or Irish phonology, just to pick three FA pages that get pretty technical.
