This is another of my previous good articles which has just received a large rewrite and expansion, pending a nomination to featured article candidacies. I'd like to check that the current form does still satisfy the GA criteria. Jo-Jo Eumerus (talk) 12:50, 27 March 2024 (UTC)[reply]
The article seems to clearly meet the GA standards still.
There is one unsuitably old source in the climate section, about the early Holoceen maximum being hotter than today. Today is much hotter than 28 years ago, ands accuracy in paleoclimate reconstructions is much much higher. There are prose quibbles I have which I can leave on the talk page. —Femke 🐦 (talk) 07:45, 30 March 2024 (UTC)[reply]
Are you familiar with more recent sources that discuss the Norte Chico climate during the Holocene? And yes, I'd like to know about the prose quibbles, if I may ask. Jo-Jo Eumerus (talk) 10:10, 30 March 2024 (UTC)[reply]
I'm not familiar with any local reconstructions. If you look at this 2022 reconstruction, you see that the pre global warming peak temperature at 23 S didn't take place in the early Holocene, but more like the late Holocene. —Femke 🐦 (talk) 10:29, 30 March 2024 (UTC)[reply]
and the active lithium prospect "Proyecto Mariana" at Salar de Llullaillaco. I know it usually takes over 10 years to open a mine, but with lithium in high demand a more recent update would be good here. —Femke 🐦 (talk) 07:50, 30 March 2024 (UTC)[reply]
Llullaillaco has been active in historical time, making it the highest historically active volcano on Earth. Mid-sentence cites impede readability. Sometimes they're unavoidable, but here the first sentence fragment is completely unnecessary, as it's already implied by the second sentence fragment
Sentences are often a bit too long for nice flow. For instance, you can split the sentence about the ceremonial path like this: A ceremonial Inca path, starting from the tambo, leads up to the volcano. Spanning 1.5–2 metres (4 ft 11 in – 6 ft 7 in) in width, it narrows on steep sections and is delineated by wooden posts and cairns, likely to ensure visibility under snow cover. I use ChatGPT for this kind of copy-editing a lot, asking it to improve flow or write things more concisely. Might be an idea for the top-20 long sentences in the article.
It is most often associated with either convective or cyclonic activity during summer and winter, respectively --> the word respectively forces a reader to reread earlier parts of a sentence to match elements. Here, you can rewrite as "It is most often associated with either convective activity during summer or cyclonic activity during winter".
Only a few climate data are available on Llullaillaco --> This will feel grammatically ambiguous, given that data is usually not used as something countable. You can use alternatives such as "Limited climate data is available on Llullaillaco"

Most of the issues with prose go beyond the GA criteria, so opening a section here.
You write very densely and with a lot of numbers. That means that conversions into American units like feet quite strongly impede readability. Per MOS:CVT, scientific articles don't require these conversions. I would maybe only convert on first mention, and omit it later. Or omit it altogether.
The view from the mountain extends from Licancabur to the north over the Nevados de Cachi mountains in the east to[6] Ojos del Salado 250 kilometres (160 mi) to the south,[33] as well as on mountains between these and Llullaillac. It took me 3 tries to understand this. Split the sentence and reduce mid-sentence cites. —Femke 🐦 (talk) 13:21, 30 March 2024 (UTC)[reply]
with temperature maximums ranging −8 – −13 °C (18–9 °F) between summer and winter. This is a bit ambiguous. Does it mean with temperature maximum ranging from -13 in winter to -8 in summer? —Femke 🐦 (talk) 13:24, 30 March 2024 (UTC)[reply]
Deposits in Quebrada de las Zorritas valley indicate that between 2,436.8 ± 49 and 1,593.1 ± 36 radiocarbon years ago runoff was more intense. False precision: no need to have a year fraction here. Also note that the source is very old, so "years ago" doesn't quite work. —Femke 🐦 (talk) 13:27, 30 March 2024 (UTC)[reply]
