Talk:List of volcanoes in the United States

message: According to my understanding, Plutons are igneous formations, but they were not necessarily volcanoes, as they didn't necessarily erupt. Here are the plutons that I have found in the list so far: Whitevelcro (talk)
===Malapai Hill===
Malapai Hill is a Intrusive rock, which is an underground volcanic formation. I'm not sure whether this counts as a volcano. The rock is volcanic in origin, but it did not erupt. I believe it would be more reasonably categorized as a Pluton than as a volcano. I'd prefer a clarification from someone who knows more about geology or volcanology to make sure.

message: ===Organization===
Alaska has a lot of volcanoes that are parts of close groups or even stratovolcanoes, but there isn't any indication of this on the list. I don't see a precedent for smaller groupings of volcanoes on any of the other volcano lists, but it may be useful on a list this large.Whitevelcro (talk)
===Cold Bay / Frosty Peak===
Cold Bay Volcano listing here:  No such thing, really.  The coordinates given here are for Mt. Frosty, a volcano within the Cold Bay volcanic complex.  Not sure how to go about renaming this link, however, as it goes to a "Cold Bay volcano" page.Idocrase 00:24, 26 January 2007 (UTC)

message: I believe that Buzzard Creek is inappropriately linked. The main Wikipedia page references a small creek in South Dakota. The coordinates listed point to a nondescript semi-forested hillside in Alaska with no apparent volcano-like features in the near vicinity. In the absence of a suitable alternative name or evidence of the volcano I would advocate for removal, but I will wait for alternative opinions/guidance.

message: I've been adding entries to the Arizona section and it is getting pretty big so I got to thinking, would it make sense to list individual vents and cones belonging to a particular volcanic field with that volcanic field rather than in this category?  These would be features of a particular site of volcanism rather than unique volcanoes.  Exceptions could be made if there is a compelling reason, if the site is a stratovolcoano or a case like Lassen Peak.  Thoughts? --Burntnickel 00:38, 4 May 2007 (UTC)

message: I think it might be nice if the list mentioned whether the volcanoes are still considered active or not.  —Preceding unsigned comment added by 221.186.127.18 (talk) 00:52, 27 February 2009 (UTC)
replies: text: That's actually a lot harder than it seems.  Geologists don't actually classify volcanoes that way.  It's more of an "evening news" sort of classification.  See Talk:Mount_Hood#Dormant or active.3F for a discussion of whether Mount Hood is active or dormant.  —EncMstr (talk) 00:56, 27 February 2009 (UTC)

message: If the list is going to include long dead volcanoes, can Garrett Island (Perryville, MD) be added? From what I've read, when it was active, it was an off-shore volcano. For that matter, the USGS says that there were volcanoes all over Virginia, the Carolinas, Georgia, Maryland, etc. Elemtilas (talk) 22:30, 15 June 2010 (UTC)

message: Why are there listings for lava fields? They aren't volcanoes, rather the product of a volcano. They should be removed since a list including lava fields would greatly expand what is already going to be an overwhelming list! Newberry Volcano in Oregon has probably hundreds of lava fields on it's flanks. But they all came from Newberry, a single volcano. If no one protests, I will begin removing listings for lava fields.

message: The list says it erupted 640,000 years ago but it has erupted about 10 times since then. The most recent eruption was something like 70,000 years ago and phreatic steam explosions have occurred in the lake - maybe more recently. Perhaps this should be noted in the list Senor Cuete (talk) 16:11, 22 April 2011 (UTC)

message: I have long studied Colorado's volcanic past and noticed the Summer Coon Stratovolcano was not listed. I've added it but have never created a Wikipedia page so I could use some pointers. Summer Coon is a 34 million year-old stratovolcano that has been completely eroded down to its base and has some of the best preserved radial dikes in the US.

message: For the most part, I am satisfied with the what is listed. However, the inclusion of a few of these older volcanic, like those in Michigan and Missouri structures is a bit questionable. If the page includes those, this page could be absolutely crammed with very ancient volcanic structure, especially in Minnesota, Wisconsin, and Michigan. So, does is there a systematic approach to inclusion here? — Preceding unsigned comment added by Trilobite12 (talk • contribs) 01:00, 12 May 2021 (UTC)

replies: text: I think adding the activity classification (extinct, dormant, etc.) could get messy because there’s debate on that subject for multiple volcanoes but I would welcome a type classification for stratovolcano, shield, cinder cone, etc. DJ Cane (talk) 22:27, 7 January 2024 (UTC)
