This template was considered for deletion on 2011 August 7. The result of the discussion was "keep".

Purpose

The purpose of this template is to provide a navigation box for all of the active volcanoes in the Cascades of California/Oregon/Washington/British Columbia. I have listed the volcanoes north-south from BC to Cali. Suggested placement: bottom of the page. Gwimpey 00:08, 6 March 2006 (UTC)[reply]

McLoughlin and Jefferson

There might be question as to whether McLoughlin and Jefferson are "active"... but they are notable volcanoes. Gwimpey 07:30, 6 March 2006 (UTC)[reply]

What makes these volcanos notable? Without objective criteria, we're pushing a POV. Night Gyr (talk/Oy) 14:48, 12 December 2006 (UTC)[reply]

Change to title-link in template

Because it's called "Cascade volcanoes", it gets placed on summits that aren't in the Cascade Range - there's a big difference in the two phrases; so I changed the title and its link to the proper Cascade Volcanoes, as well as added two more BC volcanoes; others may also be notable but those two definitely, although Garibaldi is obviously much more famous south of the line for some reason. See Talk:Cascade Volcanoes, and also Talk:Cascade Range for discussions of the difference between the two terms.Skookum1 07:48, 15 January 2007 (UTC)[reply]

Mount Silverthrone

Just a note about Mount Silverthrone, it's ok to keep the volcano in the template because the Pemberton Volcanic Belt, which includes Silverthrone, is usually merged with the Garibaldi Volcanic Belt, which is the northern extension of the Cascade Volcanic Arc. This makes Silverthrone the northernmost volcano of the Cascade Volcanic Arc when the Pemberton Volcanic Belt is included. Black Tusk 06:65, 05 August 2007 (UTC)[reply]

Franklin Glacier Volcano etc.

I recently added five volcanoes in the British Columbia section because they are suitable as major volcanoes. Franklin Glacier Volcano appears to have the lowest elevation of all Cascade volcanoes in the template, but according to here (which was published in 2008), it is a large volcanic complex and therefore it is a major volcano. How do I know the seconed northernmost red star in the Garibaldi Volcanic Belt on that image is Franklin Glacier Volcano? From using coordinates and the Garibaldi Volcanic Belt map here, making Silverthrone the northermost red star/large volcanic complex in the Garibaldi Volcanic Belt. The reason Franklin is not grouped with other volcanoes on the Garibaldi Volcanic Belt map here is because it is currently not known to be part of any volcanic groups like Silverthrone, Cayley, Meager or Garibaldi. User:Seattle Skier, I do not know where you get your material, but classifying Franklin as a small group of eroded outcrops and not a "Major Cascade Volcano" by any standard is incorrect. Perhaps you got your infomation from an older source, which likely wouldn't be very reliable for present-day classifications. Newer references, such as the first one (2008), are a lot more reliable, especially when it comes to a government source (e.g. Natural Resources Canada, which is the publisher of the 2008 image and page here). There probably is volcanic outcrops at Franklin, but those outcrops would most likely be part of a larger feature. Franklin itself is a large caldera complex like Silverthrone and therefore size is what matters rather than height, which is apparently what your excuse is for not allowing Franklin to be included within the template. I recently looked at Franklin myself using satellite software and it appears to be larger than Garibaldi, Cayley, Meager, Baker etc. Seattle Skier, if you have a problem with Franklin and others being a "Major Cascade Volcano", I guess you still have to learn more about those volcanoes. Franklin, Silverthrone etc have been around way longer then you have. Black Tusk (talk) 22:37, 20 December 2008 (UTC)[reply]

And according to your issue with the large gap between Meager and Franklin, such gaps exist throughout the Cascade Volcanic Arc (e.g. between Garibaldi and Baker) and most of that area is largely unexplored, giving a possibility for volcanoes in that area. But still, Silverthrone and Franklin are considered to be products of Cascadia subduction based on age, rock composition and chemistry. I have permission to let GSC (Geological Survey of Canada, which is a portion of Natural Resources Canada) volcanologists know which Canadian volcano areas are getting questions for which there are no posted answers. Since then, I have somewhat allied with the Geological Survey of Canada for a number of reasons: it takes a long time to get material and other things into the Geological Survey of Canada system, including updates and postings. I would be interested to here why you feel Silverthrone and Franklin should not be included. Thanks. Black Tusk (talk) 22:48, 20 December 2008 (UTC)[reply]

There is not a single volcanologist or WP:RS that would ever claim that Franklin Glacier complex is a "major Cascade volcano", can you find one? Even the Geological Survey of Canada says this about Silverthrone: "Its affinity is unclear because it has been only minimally studied." [1] and this about Franklin: "Its tectonic affinity is unclear because it has been only minimally studied." [2] In each sentence, "Its affinity" refers to whether it is part of the Garibaldi Belt and caused by the present Cascadia Subduction Zone or not. That's it, they don't know the answer yet. So neither of those really should be included in the template about Cascade volcanoes at all, or they should be italicized and footnoted if included.

I very much doubt that you are "allied with the Geological Survey of Canada" as you claim, but if so, then find evidence to support your claim for inclusion. Read Wikipedia:Verifiability and the section "Burden of evidence". It is up to you to find evidence to support your claims for inclusion of material on Silverthrone and Franklin in the Cascades. Otherwise, that material must be deleted per WP policy. --Seattle Skier (talk) 01:58, 24 February 2010 (UTC)[reply]

You doubt lots about things. Who says Franklin is not major? Where does your major volcano classification come from? Find sources for those statements. A volcano 20 km long and 6 km wide can easily be considered a major volcano; that is larger than Garibaldi, Meager, Cayley and other Cascade volcanoes that are currently in the template. Why would it matter if Franklin has little eruptive material? That would more or less be related to a major eruption. A possible explanation for the little amount of volcanic material would be because it is eroded. I had access to Catherine Hickson until 2008 when she was part of the GSC and I still have access to another volcanologist. When they found out about my contributions on Canadian volcano articles, they were happy to give me support. And I support them by adding volcanological information to Canadian volcano articles because they do not have the time to do updates. In fact, I still have access to Cathie even though she has left the GSC. And guess what? She considers Silverthrone and Franklin to be Cascade volcanoes. There is a map here on page 77 that describes Franklin as a large volcanic complex along with Silverthrone, Meager, Cayley, Garibaldi and Baker. A large volcanic complex is basically the same thing as a major volcano; large is synonymous with big, major is synonymous with big, major is synonymous with large and large is synonymous with major. Yet, you keep on saying Franklin isn't major. I would like to see where you get your "info" from. BT (talk) 21:45, 25 March 2010 (UTC)[reply]
