Talk:Manicouagan Reservoir

Global consequences of the Manicouagan Event
I'm curious what the ecological and physical outcomes of this impact was. Is there an extinction of species attributed to this? How long was the atmosphere disrupted? — Preceding unsigned comment added by 69.24.84.136 (talk) 13:19, 17 January 2023 (UTC)

The Triasic terminator is 213mya per several reputable sources, one being the USGS and another the Canadian Museum. 1)USGS: http://vulcan.wr.usgs.gov/Glossary/geo_time_scale.html 2)Canadian Museum: http://park.org/Canada/Museum/extinction/timescale2.gif You may want to review your http://en.wikipedia.org/wiki/Manicouagan_Reservoir. text. The Impact 212+/-2mya does coincide with the Trassic terminator date 213mya.

Dang. This thing DOES look like Strong Sad. UndeniablyJordan 03:21, 21 February 2006 (UTC)

Yeah, they even made a joke about it in an easter egg of the new strong bad email

Split articles?
Most impact craters have their own articles. But while this is one of the larger impact craters on Earth, its article is tacked onto the reservoir article, which is important in itself. I'm giving notice that I intend to separate into two linked articles, in the process beefing up the impact article with more references. --Zamphuor 15:32, 5 April 2007 (UTC)

Strong Sad
No mention that it looks exactly like his head? It even has the disturbing soft-serve flip! —The preceding unsigned comment was added by 75.72.21.221 (talk) 18:17, 14 April 2007 (UTC).
 * It was here for a while, but that is better suited to Strong Sad's article. --Jnelson09 20:38, 8 June 2007 (UTC)

They even shows a comparison in sbemail 146 in an easter egg!

1,950 square metres? It's much larger than that. That's only a couple of acres.

How to pronounce it?
I was disappointed that there wasn't any hint how to pronounce "Manicouagan", and that I had to go to http://www.pronouncenames.com/pronounce/manicouagan to find something. Maybe this could be added? (Otherwise, good job with the article.)DavidHobby (talk) 02:55, 18 May 2013 (UTC)

Original size and shape of lake?
I'm curious about the original size and shape of this lake. Was the Daniel-Johnson dam the first human damming of this lake? Did the lake exist before, or was it a series of lakes? --Neurogeek (talk) 17:08, 24 July 2014 (UTC)


 * The previous two lakes looked like this: http://www.staff.science.uu.nl/~rutte101/stuff/manicouagan/1962MapManicouaganMushalaganLakes.jpg taken from http://abioticdesignstudio.blogspot.com/2014/01/the-eye-of-sauron-reservoir-manicouagan.html I've seen old survey maps showing it.  It would make a good addition to the page.24.12.61.229 (talk) 04:26, 28 February 2016 (UTC)

Merge with Manicouagan crater
Judging on above, Manicouagan crater was split from here back in 2007 by, but I don't think it was necessary, because the crater and the reservoir are largely coterminous, and readers would be better served by a single article. The crater article does not seem to contain much more information beyond what is found here (mostly the "Hypothetical multiple impact event" section that could be gracefully merged here), and just being a large and important crater does not require having a separate article. By quick perusing of Impact cratering on Earth, most impact crater articles are either at "X Lake" or "X Crater", but are not split like this one. No such user (talk) 14:30, 12 April 2017 (UTC)


 * I went ahead and merged the articles. No such user (talk) 14:14, 25 April 2017 (UTC)

SIXTH largest
In the article impact craters it is rated as 5th largest -- also in the simple english wikipedia at the article M. crater. pietro151.29.163.236 (talk) 11:31, 2 December 2017 (UTC)


 * It is fifth, not sixth. I don't have time to fix it at the moment but here's a decent source: https://news.nationalgeographic.com/news/2013/13/130214-biggest-asteroid-impacts-meteorites-space-2012da14/ SentientParadox (talk) 05:40, 24 April 2018 (UTC)


 * I've changed the text but I'm not versed in how to add the reference and citation. SentientParadox (talk) 05:44, 24 April 2018 (UTC)


 * Never mind. I missed the source already cited, which is newer than the NG reference I found so I reverted my aforementioned edit. Seems the other articles you mentioned need to be updated. It is late so I will leave it up to someone with more time who happens to stumble over this. SentientParadox (talk) 05:56, 24 April 2018 (UTC)


 * May I make a suggestion. We have here a group of localised craters, of similar size and assumed date, all about -200Ma.
 * We have in the British Isles, Ireland, to be precise, A river valley which very closely follows about 120 degrees of arc of a very good circle. The Shannon Valley.  The other 240 degrees are missing, at least, they are nowhere near Ireland.  I believe I have found much of the remainder of the circle in Newfoundland, and Southern Greenland.  At the centre of the circle, of which the Shannon valley forms an arc, there are two loughs which almost meet at right-angles.  If you now zoom right out to include Scotland, it is clear that the Great Glen is aligned with this crossing point, and this line crosses two major loughs.  Switching to terrain mode, it is now clear that the Eastern coast of Ireland is backed by major hills which also form an arc around the crossing point, and yes, we can find another ring section.  It is the Irish Sea!  Further out we come to the the hills and mountains of West Wales.  Slipping further out we have another ring section, starting with the Isle of Aran, to the Galloway Forest Park, the Lake District, the Yorkshire Dales and the Pennines, the Cotswolds, and through to the Cornish Peninsular.  We are seeing a ring structure 800km diameter.
 * This impact would have 'splashed' much of the debris into solar orbit, where it would remain for millions of years in Earth Crossing Orbits. Earth crossing orbits often involve collisions, so Lake Manicouagan is probable formed by one of these Earth crossing Debris Remnants.  The appearance is that it was large enough to be broken up into half a dozen pieces about the same size. 2A00:23C6:4086:BE01:380B:8E99:283C:E837 (talk) 20:23, 20 May 2022 (UTC)
