Valley of the Lower Mississippi River."
In 1944 the U.S. Army Corp of Engineers commissioned the "Geological Investigation of the Alluvial Valley of the Lower Mississippi River." An Associate Professor of Geology at Louisiana State University named Harold Fisk, Ph.D. produced these amazing colorful plates representing the changes the path of the Mississippi has taken over its history. This is just one of the many plates he made and I think it makes a beautiful fabric!
