Talk:Mount Takahe

8200 or 7900 eruptions
I got a feeling that the eruptions 8,200 and 7,900 years before present are actually the same event, but I am not sure if the source can be interpreted that way - that source defers to this one which mentions no 7,900 event but does have the 8,200 one. Also, should the 8.2 ka eruption in this abstract be considered the same source? Jo-Jo Eumerus (talk) 17:37, 17 March 2020 (UTC)

SG review
Jo-Jo, I will slowly add as I have time.


 * is a 3,460 metres high snow-covered shield volcano
 * This has the same hyphenation problems we discussed at Coropuna. It would correctly be hyphenated as "3,460-meter-high", which introduces too many hyphens, especially with the convert, so the sentence is better recast to avoid that mess ... is a snow-covered shield volcano that is 3,460 meters high and stands 200 kilometres (120 mi) away from the Amundsen Sea ...


 * ... is a c. 30 kilometres (19 mi) wide mountain with an up to 8 kilometres (5.0 mi) wide caldera and parasitic vents.
 * Same problem. Correctly hyphenated, it would be 30-km-wide mountain with ... 8-km-wide caldera ... which is a mess with converts and hyphens, so best to recast sentence entirely ... It is a mountain with parasitic vents that is 30 km wide with a caldera that is up to 8 km wide.

The kind of incorrect hyphenation I mention in the first two points is throughout the article; I can check back after they are all fixed, Best, Sandy Georgia (Talk)  00:29, 22 April 2020 (UTC)
 * formerly it was thought that it had formed entirely underneath of ice ... I am not sure what this means ... had formed entirely below ice ?
 * Yes. I wasn't sure of the ideal formulation there, but your version is clearer - changed it to that. Jo-Jo Eumerus (talk) 09:01, 22 April 2020 (UTC)
 * With a volume of 780 km3 (190 cu mi) it is a massive volcano, the parts of the edifice that are buried underneath the West Antarctic Ice Sheet are probably even larger. ... has incorrect punctuation.  ??? It is a massive volcano, with a volume of 780 ... and probably even larger parts buried beneath the West Antarctic Ice Sheet ??
 * Changed it to semicolon, but I am not sure that this works better than current. It's a bit hard to formulate. Jo-Jo Eumerus (talk) 09:01, 22 April 2020 (UTC)
 * It is located within the West Antarctic Rift System along with about eighteen other known volcanoes. ... move that earlier in the paragraph?
 * I think that moving from the specific to the general is a better structure to use, here. Jo-Jo Eumerus (talk) 09:01, 22 April 2020 (UTC)
 * The volcano was active in the Quaternary. Radiometric dating has yielded ages of 300,000 years and less for its rocks, the fast-growing volcano reached its present-day height about 200,000 years ago. ... has incorrect punctuation.
 * Used a dot here. Jo-Jo Eumerus (talk) 09:01, 22 April 2020 (UTC)
 * A number of tephra layers encountered in ice cores ... found in?  Encountered in sounds passive ... someone had to go look for them, no?
 * Yes, but since we are talking about a volcano here and not about the people who drill for them (and neither do the sources for this article) I think passive voice works here. Jo-Jo Eumerus (talk) 09:01, 22 April 2020 (UTC)
 * Ah, that kind of hyphenation issue. I did check some style guides and it looks like the second hyphen is needed, so added it. I don't think that recasting the sentences is the better solution, it makes them much longer and wordier and sound a little off too. Jo-Jo Eumerus (talk) 09:01, 22 April 2020 (UTC)
 * BTW, the convert template will handle it, with the "adj=mid|-wide" construct. If the units are abbreviated, it intentionally drops the hyphen between the number and unit. 10 km vs. 10 km. Note that you do have to specify the target unit when using that construct. -- JHunterJ (talk) 14:19, 24 April 2020 (UTC)
 * (ec)Huh, didn't know about that parameter . Thanks. Also, seems like I might have messed up the first ping to . Jo-Jo Eumerus (talk) 14:24, 24 April 2020 (UTC)
 * No time to look today ... finish addressing per JHuntrJ, ping me tomorrow to remind me ???? Sandy Georgia (Talk)  14:32, 24 April 2020 (UTC)

Further SG review
Jo-Jo, starting over because I forget where I left off; my apologies if I hit something already covered. I think you're probably good to go to FAC. Good luck! Sandy Georgia (Talk)  21:40, 29 April 2020 (UTC)
 * Snow, ice, and glaciers cover most of Mount Takahe; formerly it was thought that it had formed below ice. ... It is a bit jarring to find something in the lead that was formerly thought to be the case, without understanding why or how that earlier thinking changed.
 * Decided to just cut this sentence; it's a bit too off-field for the lead. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)
 * the closest volcanoes are Mount Murphy, either 100 kilometres (62 mi)[9] or 170 kilometres (110 mi) north of Mount Takahe ... a 70-kilometer discrepcancy is begging for an explanation ??
 * Seems like that was a bog standard misreading; I've corrected it. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)
 * and is elongated in east–west direction. ... this is ungrammatical, but I don't know how to fix it.
 * Me neither; I've tried with a sentence split. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)
 * Is this however necessary ? Glacial erosion is not pronounced, however, with only a few corries cutting into the lower slopes. See Overuse of however.
 * I am not sure - it does sort of contradict the preceding item. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)
 * Snow is not linked on its first occurrence, rather its second ... but do snow and ice really need to be linked (WP:OVERLINK) ?
 * No; removed them. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)
 * Air temperatures recorded at Mount Takahe usually are below the freezing level,[38] wind appears to flow around the mountain. ... incorrect punctuation joining the two clauses, but I'm not sure why these two are in the same sentence.
 * I've split them; it was mostly to find a place for the wind sentence. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)
 * Not at all sure why there spaces inserted into basic number ranges; removed them all.
 * However, most of the volcano is believed to consist of mafic rocks ... is that "however" necessary ?
 * Probably yes, seeing as there is a contradiction. Jo-Jo Eumerus (talk) 09:41, 30 April 2020 (UTC)

Human activity?
One of the main things I became curious about once I opened this page was whether humans have ever climbed the mountain. However, the page currently only includes the single line Mount Takahe was first visited in 1957–1958 and again in 1968. "Visited" is quite vague—does it mean summitted, or that someone walked up to the base, or that they just flew by in a plane? And has there been any activity since 1968? It'd be nice if the article better addressed those questions. &#123;{u&#124; Sdkb  }&#125;  talk 00:25, 18 December 2020 (UTC)
 * Added another mention of 1985. Per LeMasurier et al. 1990 it appears that the outcrops in the summit region were visited in 1985-1985 but none of them coincides with the summit exactly. Jo-Jo Eumerus (talk) 09:06, 18 December 2020 (UTC)
