Have you ever been by or on a river as it meets another? It's pretty neat. You’d think, what's the big deal, water meeting water, but no, it's way cool.
Because each river differs in density, temperature, turbidity (we love this word), and electrical conductivity, etc. the mixing can be nice and slow.
We like to think of it as folding egg whites in rather than throwing something into your Vitamix…that's just us though we are absolutely not scientists.
Anyway, here at RCC we highly recommend you find your nearest confluence and witness it for yourself.
I mean, why wouldn't you?
