The scale of this river blows my mind - I can't relate, maybe the Volga when I traveled through Russia is what comes closes to the scale of the Missouri River - But I'd have to visit the US to compare ;-)
Thanks for sharing with us a piece of history and context - curious to see the follow-up post :-)
The Volga also drains an enormous semi arid basin. I've never seen it, but I would expect that they would be very similar. Very interesting comparison. I will probably have to do a little research now just to satisfy my curiosity.
Thanks for stopping by. Always appreciated.
