I had no idea that the Missouri River was the largest in North America. There is always so much talk about the Mississippi. The images of the river are very picturesque. It is a shame that so many of our great waterways are at risk. Freshwater is so important and so many things depend on access to it. I am so happy that you included the section about the buffalo hunt and how the river has played an important role in the lives of the native peoples in this area for so long. That is some history that is so important to share.
