Apparently mislabeled waterglasses[edit]

The the glasses of water depicted in the article, one allegedly containing water from Rio Negro, are apparently mislabeled. The water of a blackwater river surely would appear darker in direct comparison to a water of a whitewater river.

Shrunk Head[edit]

I find pictures of shrunk heads disturbing AND I find it annoying that there is one here. Ok, so the Jivaro living near the river kill people and shrink heads. Is it really SO relevant to the river to deserve a picture of a shrunk head? There is no such picture even in the Jivaro's article. Come on. I'm getting rid of that head now. — Preceding unsigned comment added by Cloudyed (talkcontribs) 09:01, 19 October 2018 (UTC)

I am not the one making changes[edit]

I just wanted to let it be known, I have received a couple of messages informing me that "my" edits to this pages will be reverted. I have never edited this page. That is all. — Preceding unsigned comment added by (talk) 17:24, 26 June 2018 (UTC)

Length value[edit]

As the current value for the length (6992.6 km) comes from an unpublished study, and is not representing the scientific majority[1], I changed it according to WP:RS to the Encyclopaedia Britannica value ("at least" 6400 km[2]) which seems to have general agreement, is a reliably published value, and is used throughout the web (simply search for amazon river "6400 km"). For clarity I added a note describing the origin of the value.

Although personally I would prefer to use the value of 6575 km published in a peer-reviewed journal.[3] Because IMHO it is the best source available. It is very well documented, reflects upon the whole problem of the existence of lots of length values without source, and it is done with the most modern mapping tools available. But I think this should not be done without a proper discussion. So I invite all fellow Wikipedians to discuss the possible introduction of 6575 km as the accepted length of the Amazon. A decision for either one is difficult, the Britannica value seems to be one that is generally accepted and a simple internet search (see above) shows its impact, on the other hand we do not know where it comes from and who measured it. The Liu et al. value seems to be measured with scientific care but has not yet gained much attention. --WEGC1 (talk) 17:24, 31 December 2018 (UTC)

Geology Section[edit]

The geology section either needs a lot more detail about the "Amazon/Congo" river system, or it needs to not mention it. The only place I can find mention of such a river system is in this article or places that quote this article.Rockphed (talk) 18:08, 19 August 2019 (UTC)
