@GregCocks Oooh, love that third map, didn't realize people plotted things like that...
@ai6yr a famous map, from the 1940s, by Fisk, such beautiful, well constructed and fastidious work!

@GregCocks Wow! Phenomenal, I will have to read more about that analysis technique...
I downloaded these pics of Fisk's map of lower Mississippi years ago. Love them.
@sadele2 @GregCocks Those are SO awesome (and informative... cool to see that)
Also found I downloaded this 2014 piece from Slate by Rebecca Onion on 11-foot map of the Mississippi (without avulsions) from 1866. Aimed at steamship travelers. Not terribly practical. You could rewind it into canister but had no take up reel so it just unscrolled...wherever.

@sadele2 @GregCocks Oooh, those are fun. Yeah, not practical... but neat anyway.
@sadele2 @ai6yr have you read about the Tabula Peutingeriana?

@GregCocks @sadele2 hadn't heard of that either! I made my way into the mapping world only recently, from software into GIS... this stuff is awesome!
No, hadn't heard of it. Fascinating. Went down rabbit hole of trying to remember where I saw Roman roads on hikes in Lancashire UK decades ago.
