I have never seen this map before:
I sharpened it a bit, so that I could read, with my Getting Old eyesight, the smaller river names with a bit less difficulty.
It is map number 7 of these 45 maps. A Twitter posting last night, now way down in my feed, showed one of these maps.
My favourite piece of geography there is probably Chicago, where it seems that they have a river which flows into the Mississippi. Blog and learn.
You may have heard that the Mississippi River is mighty, but if you ever doubted it, just take a look at this map. You’ll see that an extraordinary number of the United States’ rivers and tributaries send water into the Mighty Miss.
I love the names. Milk. Yazoo. Republican. Canadian (nowhere near Canada). Powder. Smoky. In general, I love the names of American places and geographical features. They seem impossibly exotic compared to the names of places in England. (But I’m sure that, for quite a few Americans, it must work the other way around.)
England has no big rivers. The Thames would hardly merit a name on the above map. I recall that one of my better pieces for Samizdata was about how the application of steam power to river transport entirely passed us Brits by. We went straight from stationary steam engines in coal mines to steam engines on locomotives. Unlike America. Yes, here.
