Talk:El Peñón de Guatapé

Questions

I enjoyed this article about a beautiful part of Colombia, but I have some questions: (1) Does "penon" mean "rock" or "rock view"? (2) Is the rock's mass 185 cubic meters? That doesn't seem correct. (3) I would guess the rock was first climbed in 1954 but I don't want to change the article since I know nothing about it. (4) Are you sure that the new species is named Pitcairma heterophila? (5) Do you know the name of the person who named the new plant species? I apologize for editing the article, but there were several minor English mistakes. Estoy segura, que hago muchos errores cuando yo escribo o hablo en espanol.Philippachaucer (talk) 15:20, 7 June 2009 (UTC)

Is hard to translate Penon. it is my understanding A Penon might be the act of viewing from a tall place, but I might be wrong and a Penol might be the rock itself. 2)Can't answer it , but it definitely makes sense 3)I doubt that rock was first climbed at that time. I believe it was known and climbed to the indigenous people of the area. 4)Can't answer that either.--Camilo Sanchez (talk) 07:35, 29 June 2009 (UTC)

Name change

I suggest this article to be renamed with its correct name. (El Penon de Guatape) and make a redirection with the mistaken popular name El Penol. Thanks. Note: Should this article remain with its wrong name I will boldly make the edit myself. Thanks again. --Camilo Sanchez (talk) 07:35, 29 June 2009 (UTC)

Composition

The "Composition" section contains mostly information which is irrelevant to the composition of the rock. Can someone think of a better way of organising this information? 14.202.125.23 (talk) 11:03, 25 April 2016 (UTC)

Volume of El Peñón

According to the article, El Peñón is 22 cubic megametres which is absurdly massive--slightly larger than the size of the moon (1.002x). This is especially extraordinary considering the weight of the rock is estimated to be 66 million tonnes so it would have a density of only 3×10^-12 g/cm^3, meaning it would be hundreds of millions of times less dense than air. — Preceding unsigned comment added by 173.196.215.72 (talk) 04:46, 30 July 2017 (UTC)

The moon comparison is wrong. The moon has a volume of 22 * 10^19 m³, which is 10 billion times more than 22 Mm³ ... But still it can't be right. The rock is about 285 m long, 110 m wide and 200 m high. So even if it was a cuboid there'd only be a maximum volume of 285 m * 110 m * 200 m = 6.27 Mm³. In fact, it doesn't fill the whole cuboid, probably max 2/3 of it, so it'd probably be something in the ballpark of 4 Mm³. This also fits the number of 10 million tons of weight that I have read at various sources (granite has a density of about 2600 kg/m³). I'll remove the fact until somebody comes up with a proper professional estimate. -- H005 (talk) 14:33, 21 April 2018 (UTC)

Geology sources I have looked upon does not mention the volume. It seems irrelevant and difficult to define to geologist. Instead I would guess estimates for the volume of Antioquia Batholith may exist. Lappspira (talk) 15:07, 21 April 2018 (UTC)

National monument

According to the article, the rock became a national monument in the 1940s, the only source given being "Guatapé's Major Office" (introduced with this edit). I didn't find any evidence of this in official or reliable sources. The web page cited is not in the wayback archive. To top, according to es:Anexo:Monumentos_nacionales_de_Colombia the system of national monuments has not been introduced in Colombia before 1959 - and the list also does not mention this rock.

So, unless someone comes up with proper evidence of this fact, I'd rather have it removed. -- H005 (talk) 09:20, 5 November 2021 (UTC)

Shrine

Does anyone know when and how the shrine was constructed? This information is not listed. Jachra (talk) 17:18, 28 April 2022 (UTC)
