This is closely related to Ice Peak Formation, so I might as well review this one too. I’ll get to it shortly. I₂Overcome ^talk 22:45, 10 October 2025 (UTC)[reply]

• Note: Instead of listing minor grammar corrections and easy fixes here, I'm just going to fix them myself as I go through this time.
• I think MEVC map.png should be moved to the Geography section, since it is a geographical map, not a geological one, and it has nothing specifically to do with the Raspberry Formation.

  The map still shows the location of the Mess Creek Escarpment in relative to the Mount Edziza volcanic complex which is mentioned in the stratigraphy section (the Raspberry Formation is part of the Mount Edziza volcanic complex after all). I could argue the Mess Creek Escarpment and the Mount Edziza volcanic complex are both geographic and geologic features since they consist of volcanic rocks that were deposited in the last 8 million years or so. In fact, the Mount Edziza volcanic complex is in the Lexicon of Canadian Geologic Units. Volcanoguy 01:08, 12 October 2025 (UTC)[reply]

  I'll leave it up to you, but I still think putting it under the Raspberry Formation subheading is oddly random. I₂Overcome ^talk 00:48, 17 October 2025 (UTC)[reply]

• Since this is an article for a geographical feature, is there anything that is worth saying about climate, ecology/wildlife, or the history of the area? This article is somewhat heavy on geology.

  Such information is available for Mount Edziza Provincial Park but not for the escarpment itself. There's more geologic information than geographic information. Volcanoguy 01:08, 12 October 2025 (UTC)[reply]

  That's fine. I₂Overcome ^talk 00:48, 17 October 2025 (UTC)[reply]

• established in 1972 to showcase the volcanic landscape Although the source uses the word "showcase," it uses it to describe what the park contains, not why it was established.

  Changed "showcase" to "preserve". Volcanoguy 19:42, 15 October 2025 (UTC)[reply]

• Consider reordering this section so that all formations are in order of youngest to oldest, or move the Basement subsection before the others.

  That's not how it's ordered in most Wikipedia articles, not even FAs. Volcanoguy 01:08, 12 October 2025 (UTC)[reply]

  That's fine then. I₂Overcome ^talk 00:48, 17 October 2025 (UTC)[reply]

• fifth oldest geological formation → youngest geological formation?

  Done. Volcanoguy 02:25, 12 October 2025 (UTC)[reply]

• occurred during four magmatic cycles of the Mount Edziza volcanic complex → occurred during four of the five magmatic cycles of the Mount Edziza volcanic complex This is clearer; since you only mention cycles 1-3 and then 5, the reader may be confused.

  Done. Volcanoguy 20:06, 15 October 2025 (UTC)[reply]

Subsequent subsections and Accessibility look good. I will begin source spot checks soon. I₂Overcome ^talk 05:08, 11 October 2025 (UTC)[reply]

• 57°34′35″N 130°47′58″W[1]  Done
• The escarpment was named for its association with Mess Creek, a tributary of the Stikine River which flows into Sumner Strait of southeast Alaska.[1][10][11]  Done
• Rocks: Comendite, trachyte, hawaiite, alkali basalt[5]  Done
• Hunting, camping, fishing, hiking, wildlife viewing and nature studying are some of the activities available in Mount Edziza Provincial Park.[16]  Done
• This segment is drained by at least four unnamed tributaries of Mess Creek, which is less than 760 m (2,500 ft) in elevation.[2]  Done
• They were highly fluid and mobile at the time of their eruption, as evidenced by their extreme persistence and relatively narrow thicknesses; individual basalt flows of this geological formation are less than 3 m (9.8 ft) thick. The source of these lava flows was probably a cluster of vents further to the north called Sezill Volcano, which may have been active prior to the onset of Armadillo volcanism.[23]  Done
• The Kounugu Member was erupted from at least four volcanoes which have also been deeply eroded and extensively buried under younger volcanic rocks.[26]  Done
• These lava flows most likely cascaded over the escarpment into the densely wooded valley of Mess Creek, but no evidence of this phenomenon has been found on or below the escarpment.[31]  Done
• The Mess Creek Escarpment can be accessed by float plane or helicopter, both of which are available for charter at the communities of Iskut and Dease Lake.[36] This type of claim needs a more recent source. The original manuscript of Souther 1992 was received by the publisher in 1985, and a lot can change in 40 years. I recommend removing the second part of this sentence if a more recent source for the locations of charter services cannot be found.  Not done

  Alpine Lakes Air has a base at Tatogga Lake (near Iskut) and BC Yukon Air has a base in Dease Lake. Volcanoguy 21:01, 17 October 2025 (UTC)[reply]

  Can you add recent sources that confirm this (perhaps company websites)? I₂Overcome ^talk 21:23, 17 October 2025 (UTC)[reply]

  Sources: [1][2]. The information is still verifiable in any case so I wouldn't quibble over this detail. Volcanoguy 21:31, 17 October 2025 (UTC)[reply]

  I would recommend citing these sources inline at the end of the sentence, in accordance with GA criterion 2b and WP:V, since I have already challenged the reliability of the one source that is currently cited. My understanding is that content that has been or is likely to be challenged has to be directly supported by a reliable source that is cited online inline. While you can say the current source "directly supports" it, it isn’t "reliable" because the source is too old (see WP:OLDSOURCES). I₂Overcome ^talk 22:16, 17 October 2025 (UTC)[reply]

  Also, it appears from the sources you provided that neither company provides helicopter service, just float planes. I₂Overcome ^talk 22:21, 17 October 2025 (UTC)[reply]

  @Volcanoguy Pinging because the 7-day hold period is almost up and I would like to get this passed. I₂Overcome ^talk 23:43, 23 October 2025 (UTC)[reply]

  The problem with WP:OLDSOURCES is that you haven't provided any evidence for Souther 1992 to be inaccurate. Volcanoguy 23:51, 23 October 2025 (UTC)[reply]

  I don’t think I need to provide evidence that the source is inaccurate when it’s an old source making a claim about currently available services. To me it seems like common sense that one sentence in a geological report from 40 years ago isn’t a reliable source of information about things that are happening today. But there is some evidence: If Alpine Lakes Air and BC Yukon Air are the only two companies permitted to fly into Mount Edziza Provincial Park as [16] indicates, then there is no helicopter service anymore, since the two sources you provided above say those two companies only have float planes. All I’m asking is that you cite the two sources you provided and remove the bit about helicopters unless you can find a source that says that either Alpine Lakes Air or BC Yukon Air has helicopters.

  @Volcanoguy I₂Overcome ^talk 03:28, 28 October 2025 (UTC)[reply]

  I will do this but I am busy at the moment so I have not have online much lately. Do the two sources I provided meet WP:RS? Volcanoguy 15:52, 29 October 2025 (UTC)[reply]

  The two closest policies for this case appear to be WP:SELFSOURCE and WP:VENDOR. The first allows using self-published sources as information about themselves as long as five criteria are met, and the second allows citing e-commerce sources for things like book titles and running times if a secondary source isn’t available. So while the website for BC Yukon Air doesn’t fall neatly into either category, I think it should be reliable only for providing information about the company that can’t be found elsewhere. I₂Overcome ^talk 21:37, 29 October 2025 (UTC)[reply]

  But just because the two companies permitted to fly into Mount Edziza Provincial Park only have float planes doesn't mean helicopters aren't allowed in the area. The BC Parks website for Mount Edziza Provincial Park claims "private aircraft are permitted to land within the park, with the exception of the lava flows (on the Kitsu Plateau situated south-southwest of Raspberry Pass) at Mount Edziza Park, from an elevation of 5,500 feet or higher". As far as I'm aware of, float planes and helicopters are both aircrafts. An alternative would be The Mess Creek Escarpment can be accessed by float plane or helicopter, the former of which is available for charter at the communities of Iskut and Dease Lake. Volcanoguy 16:14, 29 October 2025 (UTC)[reply]

  I like this alternative sentence. I₂Overcome ^talk 21:37, 29 October 2025 (UTC)[reply]

  Reworded it to the following: The Mess Creek Escarpment can be accessed via charter aircraft from Dease Lake and Tatogga Lake, the latter of which is near the community of Iskut. Volcanoguy 03:08, 30 October 2025 (UTC)[reply]

  Looks good, but you still need the BC Yukon Air source ([2] above) for Dease Lake. You can probably also remove the Souther citation there if you want. I₂Overcome ^talk 03:36, 30 October 2025 (UTC)[reply]

  I've used a BC Parks source instead. Volcanoguy 16:20, 30 October 2025 (UTC)[reply]

  That works. Thanks for your patience. Promoting now. I₂Overcome ^talk 22:29, 30 October 2025 (UTC)[reply]

Placing on hold until this one thing is addressed. I₂Overcome ^talk 09:02, 17 October 2025 (UTC)[reply]
