Geological Investigation of the Alluvial Valley of the Lower Mississippi River, Part II
Simply because they're truly awesome, here are two more maps from Harold N. Fisk's 1944 Report. I'm a huge fan.

Fisk, 1944. Map of ancient courses of the Mississippi River, Cape Girardeau, MO - Donaldsonville, LA (Plate 22-10)

One wonders if the Army Corps of Engineers will ever learn that treating rigidity and permanence as design orthodoxy in a landscape where instability and suppleness are supreme can only lead to catastrophic consequences, no matter how much federal money are pumped into their projects. Perhaps they have, but I see little evidence of this. And to think that India and Bangladesh, in their attempts to control the Ganges and Brahmaputra, are looking to the corps for ideas and models.

  • thank you so much for finding and posting these!! i'm a huge map fan... total amateur though... i've been trying to build my own topographical map (simple B&W line drawing) but have found it to be quite the challenge. Anyway, how did you get the above maps to show up on a white background? I have the original plates from that site but when I try to use Photoshop's brightness / contrast controls to replciate what you have above, I get poo poo. Any tips would be hugely appreciated!

  • You've done a beautiful job of making these amazing maps more accessible. Just FYI I've linked to your site from my blog since the full-size downloads are so huge.
