Ancient Canals (North America)

John Jensen some years ago called into question the origin of canals carved into the landscape of the Louisiana coast, and other areas along the American side the Gulf of Mexico.

The evidence collected of many of these canals do not match up with any known historical source, and appear to link to a time prior to European colonization of North America.
