Did not realize that when the Andes Mountains were created, the Amazon River's exit route was 'cut off' ♦♦ Very fascinating

And I liked your opening line ..where u said the Amazon River is colossal . Hadn't heard that word (colossal ) used very often here.

As to the stingray, well I took a class in Marine Biology -- so it was rather interesting to me when u explained

I hope the landscape doesn't disappear ♥ Those South americans need to get their act together & protect it (at least I hope they will)

Thank u for your thoughtful post ♦♦ It had good information

MERRY XMAS
