@bigtom13, First of all your work is really appreciable because this is deep and greatly subjected post regarding the Mississippi River. And whenever we talk about the water aspects and it's flow then that subject becomes really interesting because, there can be so many interesting inputs which we never know just exploring the pictures.

First of all i want to talk about the pictures, and through pictures i can say that, this is really breathtaking river, and picture with those flying birds just making an Picture Perfect effect. And for sure i can say that this river has to be one of the best explorative aspect.

And as you said, The lower river historically changes it’s course about every 500 years, showcase that nature is true artist because it's time to time self modify to change the course of it's cycle, and that's why i call Nature Is Everything.

I am not familiar with these aspects of The Mississippi Delta and Delta Of The Mississippi River, but good to know that difference because it's an informative subject for me and when we read without any background of it, then we can confuse between these two subjects and can consider both as one.

Keep up and wishing you an great day and stay blessed. 🙂
