I don't think I did the move request right, but there it is. I don't see these three sisters in Oregon as being more notable than the other mountain ranges or other meanings of the word so I suggest the first page be disambig. Mithridates01:52, 23 January 2006 (UTC)[reply]
Tried to move it just now but I wasn't able to move the disambig page into the main one so I just put it back for the moment. Now that I think about it I should be asleep now. Maybe someone else can help. Mithridates21:30, 23 January 2006 (UTC)[reply]
First: I tried to improve the appearance of the article. To fix the line spacing, between the three elevations, prominences and coordinates, I ran everything together on one line for each field. Look at the prior version to see the problem this fixed.
Second: I used PeakBagger as the source for elevation and prominence data for all three mountains. The prior version used NGS as the source for the elevation of the South Sister. The elevation on the NGS datasheet uses NAVD 88 while Peakbagger and the on current topo maps uses NGVD 29. I think its better to use the same datum for all three. –droll[chat]01:27, 13 January 2011 (UTC)[reply]
2a. it contains a list of all references (sources of information), presented in accordance with the layout style guideline.
All references are properly, and consistently, formatted.
2b. reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose).
All photos are valuable in illustrating the topic.
7. Overall assessment.
A finely written article, great job.
Lead
"The Three Sisters form a complex volcano comprised by three volcanic peaks of the Cascade Volcanic Arc and the Cascade Range in the U.S. state of Oregon, each exceeding 10,000 feet (3,000 m) in elevation. They are the third, fourth, and fifth highest peaks in the state of Oregon, and are located in the Three Sisters Wilderness, about 10 miles (16 km) south of the nearest town of Sisters." - Volcano used three times in one sentence. This might flow better, "The Three Sisters form a complex volcano comprised of three named peaks in the U. S. State of Oregon. It is inside of the Cascade Volcanic Arc, and located in the Three Sisters Wilderness, about 10 miles (16 km) south of it's nearest town of Sisters. Each peak exceeds 10,000 feet (3,000 m) in elevation, and they are the third, fourth, and fifth highest peaks in the state."
" The region was active in the Pleistocene epoch, with eruptions between 700,000 and 170,000 years ago from an explosively active complex known as the Tumalo volcanic center. Basaltic lava flows from North Sister overlay the newest Tumalo pyroclastic deposits, placing the age of North Sister, the eldest, at less than 170,000 years." - Is the 700,000 a typo? If North Sister is the oldest at about 170,000 years old, and the South Sister's last eruption was about 2,000 years ago, shouldn't the eruption range be from 2,000 to 170,000 years?
I don't have the Harris book, but I think that the 700,000 refers to when the Tumalo volcanic center began erupting, before the formation of the North Sister volcano. I imagine that these age estimates vary quite a bit depending on what exact rocks/deposits are measured and how, so there's not likely to be full agreement among sources. But I will ask the nominator, Ceranthor, if he can find the answer in that book. Jsayre64(talk)04:09, 4 October 2014 (UTC)[reply]
Just want to confirm that the sentence does refer to the activity timespan for the Tumalo volcanic center. I think that the current text conveys that fairly well. Do you have suggestions for clarifying that idea? ceranthor17:29, 4 October 2014 (UTC)[reply]
Just the answer was enough for this layman to understand. During the review, I constantly had to remind myself of the area as a single entity, other than just the time period of the individual mountains. That should conclude my concerns on this article, and will pass this now. Thank you for your time and effort.Neonblaktalk - 19:22, 4 October 2014 (UTC)[reply]
Flora and fauna
"... and they feature the flowers lupine, red Indian paintbrush, ..." - I think this sounds better, "... and they feature the following flowers: lupine, red Indian paintbrush, ..."
"In addition to predator bobcats, cougars, and coyotes, raccoons, martens, weasels, and American minks can be found throughout the Three Sisters area." - Instead of "can be", you should use active wording like "are" or "are also". I think American mink sounds better, but it can be pluralized mink or minks, so no need to change.

I understand your point, but I've always preferred keeping potential hazards at the end of volcano articles, since it's the most contemporarily relevant information. ceranthor01:07, 7 November 2017 (UTC)[reply]
Hi, Ceranthor. Geography is off my beaten track, but the article which is looking good from a layman's point of view. Just some minor comments from me, mostly technical.
Maybe wiki-link Oregon? It is not a very well-known US state like California, Nevada etc.
The final paragraph has three consecutive sentences with two clauses. This is nothing concerning but it looks sort of repetitive to me.
North Sister, also known as "Faith," - I think comma after quotation mark. It might be a MoS thing but as it currently is, it seems the comma is part of Faith's title.
Middle Sister also known as "Hope,", South Sister, also known as "Charity," - same as above.
The smallest and least studied of the trio, it is the youngest of the three, having been primarily built by eruptions between 25,000 and 18,000 years ago,[36] though its most recent lava flows date to 14,000 years ago, making them slightly older than South Sister's. Too long; needs to be split.
Despite its relatively young age, besides its peak South Sister has undergone significant erosion due to Pleistocene and Holocene glaciation This needs some rearranging. Despite ... besides.
Changed to "Despite its relatively young age, every part of South Sister other than its peak has undergone significant erosion due to Pleistocene and Holocene glaciation."
Three Sisters vicinity with tilt-leveling networks and electro-optical distance meters (EDMs) - why do we need the initial when there is no subsequent use of it?
In 2004 an earthquake swarm occurred with.. a comma after 2004.
Might be worth wiki-linking global positioning system.
No comments on the references, not familiar with most of them.
The whole geology/geography section might benefit from subsections.
The text on the topographic map is probably too small to be a useful image: perhaps you could wikilink to the topographic map somewhere? The USGS hazards map has larger text, but may be too specialized. How about something like File:Cascade Range map.png ? That shows the location of the Three Sisters relative to other volcanoes. Maybe cropping it to just Oregon?
@Hike395: Hazards is covered in the article's very last section. I agree that subsections might help in geology/geography. I can work on the other suggestions tomorrow when I wake up. ceranthor04:40, 25 November 2017 (UTC)[reply]
@Ceranthor: Thanks for pointing out the last section. I was expecting all of the information about geology to be contained within the Geography and Geology section. If other readers are like myself, I would suggest splitting Geology out of Geography, and combining with hazards (perhaps as a subsection of Geology?). The USGS hazards map could be appropriate in the hazards subsection. —hike395 (talk) 04:50, 25 November 2017 (UTC)[reply]
I think it would be fine to just add this image to the geography and geology section. I'm open to the idea of moving the hazards section. ceranthor15:43, 25 November 2017 (UTC)[reply]
@Ceranthor: It's looking excellent. I've found an image of Teardrop Pool here that I wanted to upload to Commons and add to the South Sister section, but the OAuth tool seems broken for me. I'll try a manual upload. —hike395 (talk) 23:35, 25 November 2017 (UTC)[reply]
Perfect! Thanks for all your additions over the past couple days. Your combined input has been invaluable, and I'm thrilled with the article's current status. ceranthor00:44, 26 November 2017 (UTC)[reply]
@Ceranthor: I'm going through the geology more carefully now: there's some contradictory information (like the introductory section saying North Sister is younger than 170,000 years but the North Sister section saying it's as old as 311,000 years). I'm digging up the sources, so may do a bit of geology polish. I'm not a real geologist -- if you want a real geologist, I would suggest pinging Vsmith. —hike395 (talk) 06:35, 26 November 2017 (UTC)[reply]
I just expanded the ecology section. According to the USGS ecoregion maps, the area around the Three Sisters lie in 4 different ecoregions (depending on elevation and location). I took some material from Cascades (ecoregion) and Eastern Cascades Slopes and Foothills (ecoregion), condensed it, and built a short new ecology section around that. (Found an interesting thesis about the ecology of the area, also --- we could further expand this section with information from that thesis). The new material was partially taken from PD USGS sources.
The feature article criteria don't address PD material --- I believe it should be OK. If other editors think it's unaesthetic, we can either back out the edits or attempt to rewrite. It may be difficult to rewrite enough to remove the PD tag, because the material includes lists of species. —hike395 (talk) 18:41, 26 November 2017 (UTC)[reply]
@Hike395: I don't have much free time today, but perhaps tonight I'll try to get around to copyediting it a bit. I'd rather not incorporate direct text from another source if that's okay. And it's not a ton of material, so it shouldn't be too big a deal to paraphrase in our own words. ceranthor20:22, 26 November 2017 (UTC)[reply]
Just got a chance to look over it - it looks good. I asked with Brian at the FAC to see if that's acceptable or not, since I don't actually know. ceranthor23:24, 26 November 2017 (UTC)[reply]
Join the choir, love collaboration and the result! Proud to have a little DYK on this feast day, talking (in a 1653 song) about the offer of spirit and mind, heart, soul and courage. --Gerda Arendt (talk) 07:48, 6 January 2018 (UTC)[reply]
