Talk:Perito Moreno Glacier

Suggested move

I think most people refer to it just as the Moreno Glacier and I think the article should be moved to that title. What does anyone else think? Worldtraveller 00:34, 3 March 2006 (UTC)

Argentinians at least call it el Perito Moreno, but I don't know about international usage. I don't think the article should be moved. It's not a specially complicated or over-long name. --Pablo D. Flores (Talk) 02:30, 3 March 2006 (UTC)

I've only heard of this glacier referred to as Perito Moreno, in both English and Spanish. Other encyclopedias also refer to the glacier under this name; I see no reason to move. -- IlyaHaykinson 06:14, 13 March 2006 (UTC)

Simply "Moreno glacier" would translate literally to "brown glacier". The glacier was named after specialist/expert (a.k.a. perito in spanish) Moreno. Leave it. —Preceding unsigned comment added by 76.178.138.99 (talk) 02:54, 19 October 2008 (UTC)

March 2006 rupture

I note that an anon contributor changed the article to note that there was a rupture in March 2006. While the same contributor also changed the Spanish language article, I couldn't find any sources for this. I don't really have any reason to doubt the authenticity of the event, but I urge any readers to find sources and add a reference to the article. -- IlyaHaykinson 06:15, 13 March 2006 (UTC)

Found and added. -- IlyaHaykinson 20:29, 25 March 2006 (UTC)

It's known that last rupture was in march 2006. There are no photos at all because It happened at night. The article is pretty good. But there should be more images explaining how ruptures happen to be. Basically it's well explained. But I guess that it would be a bit complicated to understand for someone who haven't been there.

While visiting the glacier I heard it directly from a tour guide that the ice bridge did, indeed, collapse in 2006 during the night. There are also time lapse photos of the event posted at the glacier. Pretty much before(the weeks leading up to it) and after (the next morning). —Preceding unsigned comment added by Dead monkey, inc. (talk • contribs) 03:05, 19 October 2008 (UTC)

'Rupture' in fact caused by glacier floating

I was visiting Perito Moreno glacier in March (2012), and while talking with the guide on the 'mini-trek' over the ice, he explained that the ruptures occur when the elevated water level caused by the blockage causes the glacier to float. This a bit different from the explanation in the article that the increased pressure causes the rupture. Looking at the images of the ice bridge, you can see that it forms under the water, and grows from the bottom up until the bridge collapses. I think this is a more descriptive explanation, and frankly much cooler that a straight up rupture. Thoughts? Russbird (talk) 02:19, 17 April 2012 (UTC)

Incorrect. No floating involved. When the glacier reaches the peninsula, it separates the lake in two. Only one side has a river coming in, so level rises indeed (in that half lake). But by flowing, gently, under the glacier: 1) the levels are equalised, and 2) the flow tunnel is enlarged. What remains is an ice bridge, in the air, from the glacier to the rocky peninsula. Since the glacier keeps flowing! downwards, pressure in the bridge mountsd. Until breaking point. Now we should fire that guide for lying to tourists? -DePiep (talk) 23:55, 17 April 2012 (UTC)

Added ref http://news.nationalgeographic.com/news/bigphotos/75803897.html seems to be the only one! FX (talk) 20:28, 10 August 2010 (UTC)

Found type-o

I'm assuming the "2069" entries are errors, unless I am misunderstanding and they are meant to indicate future ruptures...?

"The glacier first ruptured in 1969, taking with it an ancient forest of beech trees (Nothofagus Pumulio). The last rupture occurred in March 2 2012, and previously in 2069, 2069, 2004, 1988, 1986, 1980, 1977, 1975, 1972, 1970, 1966, 1963, 1960, 1956, 1953, 1952, 1947, 1940, 1934 and 1917. It ruptures, on average, about every four to five years."

You are right, wrong years. I have updated the list. Hard to find a source. -DePiep (talk) 15:02, 10 October 2012 (UTC)
