FASA nominations

Please set up separate sections for each nomination.

FASA nomination Jo-Jo Eumerus

I nominate Jo-Jo Eumerus for a Featured Article Save Award for Geology of the Lassen volcanic area. SandyGeorgia (Talk) 15:35, 19 February 2022 (UTC)

Discussion Jo-Jo Eumerus

• Support. The original nominator, Mav, is no longer editing, and a "Save" would not have been possible here without the intervention of Jo-Jo Eumerus, who now accounts for almost 20% of the article content. Jo-Jo should be able to display the star in their user space. SandyGeorgia (Talk) 15:35, 19 February 2022 (UTC)
• Support. Panini! • 🥪 13:21, 4 March 2022 (UTC)

SG review

This very old archived source of a now-gone page is the basis for a good deal of content. As one problematic example, it is the source of the content:

Lassen Peak and the 16 other major Cascade Volcanoes form a segment of a ring of volcanoes that circle the Pacific Ocean known collectively as the 'Pacific Ring of Fire'.[1]

This implies 17 major Cascade volcanoes (Lassen plus 16). Throughout Wikipedia articles and maps, and in various reliable sources, we find numbers of major Cascade volcanoes ranging from 13 to 18. (In fact, I don't find 17 anywhere). In this very article, where we mention a total of 17, we show an image with 15.

The newer equivalent of the old NPS page is:

• https://www.nps.gov/lavo/learn/nature/volcanoes.htm

and it links to this page:

• https://www.nps.gov/subjects/geology/physiographic-provinces.htm

which discusses 13 volcanic centers if you click on the Cascade range. How many volcanoes in those centers?

The easiest solution I can find for this dilemma is to remove the 16 and leave it vague,[1] unless one of the newer, authoritative sources has a number that can be cited.

This is the kind of issue that is concerning when using a very dated, archived version of a source that is no longer live. SandyGeorgia (Talk) 14:43, 7 February 2022 (UTC)

In the lead:

Most notable of these is the mid to late 17th century eruption and formation (Tree Ring dates) of Cinder Cone and the early 20th century eruption of Lassen Peak.

Apparently it means to say that the eruption was dated based on tree rings (?) but 1) that detail should be in the body, not the lead; and b) jargon alert, needs to be spelled out and wikilinked or something. SandyGeorgia (Talk) 14:47, 7 February 2022 (UTC)

In the newer NPS source, they thought it important to single out interesting facts that we never mention:

Represented in the park are all four types of volcanoes found in the world--shield, composite, cinder cone, and plug dome. Unlike other Cascade volcanoes, Lassen's large plug dome and composite volcanoes are in close proximity to the smaller cinder cone volcanoes that surround the volcanic center.

SandyGeorgia (Talk) 14:50, 7 February 2022 (UTC)

Answering in order:

• I think not explicitly counting works. The problem is that sometimes different parts of the same volcano are counted differently, or that two or three edifices are part of the same system.
• I actually cut the tree ring thing, because it's discussed in far more detail at Cinder Cone and the Fantastic Lava Beds.
• I've taken a sentence of the latter and put it in the article.

You've probably noticed that I am doing this a bit half-heartedly; I've been a bit down lately and this volcano is not particularly interesting, so I am only doing slow work here. Jo-Jo Eumerus (talk) 17:11, 7 February 2022 (UTC)

I'm sorry you are feeling down! I hope you at least got a good laugh out of me not knowing what LVC stood for :). D'oh :0. SandyGeorgia (Talk) 17:44, 7 February 2022 (UTC)

Jo-Jo Eumerus to what do we link the word porphyritic? SandyGeorgia (Talk) 21:13, 7 February 2022 (UTC)

Linked. Jo-Jo Eumerus (talk) 11:10, 8 February 2022 (UTC)

I am unable to tell from reading this article what became of Brokeoff Mountain; did it blow away, erode away, or some combination of the two? Mount Tehama helps a bit, but not much. SandyGeorgia (Talk) 21:21, 7 February 2022 (UTC)

Brokeoff Mountain is a remnant of Mount Tehama, as it says in the Geology article. Jo-Jo Eumerus (talk) 11:10, 8 February 2022 (UTC)

Jo-Jo, here's the problem. I've spent a good portion of my life looking at the remnants of Brokeoff Mountain, and how it would have overshadowed the massive Lassen Peak. Local yore has it that it blew away in a massive eruption. From reading Mount Tehama, I get the idea it mostly eroded away. We don't clarify which; how did it become a remnant? Can a mountain that big just erode away ? If this text from Mount Tehama is accurate and well sourced, can we say something similar: "Over time, the volcano became dilapidated from extensive erosion and hydrothermal alteration,[6] and was eroded by creeks and glaciers. ... " SandyGeorgia (Talk) 15:12, 8 February 2022 (UTC)

Added a sentence about this. My impression is that Tehama's demise isn't well understood. Jo-Jo Eumerus (talk) 15:23, 8 February 2022 (UTC)

I'm unclear why eruption is linked in the fourth paragraph of Mount Tehama and not sooner ... does that have to do with "stages of eruption"? SandyGeorgia (Talk) 21:23, 7 February 2022 (UTC)

Changed this. Jo-Jo Eumerus (talk) 11:10, 8 February 2022 (UTC)

Jo-Jo and Volcanoguy with clarification of one minor issue above, I am good to enter a Keep declaration here, having done all the damage I can do. But I did make some changes, and we should be concerned that I have no idea what I'm talking about, so I'd feel better if you both gave it a fresh top-to-bottom read to make sure I didn't introduce anything incorrect.
