Located within the Everglades National Park, is a construction of long distance canal systems for ancient canoes. This was found beyond the shell tools and shell mounds that were discovered along the same area. It was designated as a National Historic Landmark as well as added to the U.S. National Register of Historic Places in September of 2006.
The canal showcased that pre-historic people where able to engineer such complex canal system. It is approximately 3.9 miles long and is understood to be both unique in purpose as well as design. Many researchers believe that the canal was a major thoroughfare for canoe travel between the Everglades, the Florida Keys and the Ten Thousand Islands. This prehistoric canal is one of the few surviving ancient canals in the United States.
