 This is Scientific American's 60-Second Science. I'm Cynthia Graber. This will just take a minute.

 

There’s a Native American site in Ohio that appeared to be a fort. But recent discoveries by archaeologists at the University of Cincinnati show that’s not the case. Instead, it’s a two-thousand year old Shawnee water management system. It stretches out almost six kilometers. That’s much larger than what had been thought to comprise the so-called fort. It’s one of the largest such sites in the country.

What had been thought to be gates for military protection are actually a series of dams and irrigation canals. There are logs and clay bricks for damming; raceways for flowing water originate in far-off springs. The water was stored and channeled for irrigation. Drill cores show water sediments and clay.

The site demonstrates a sophisticated knowledge of engineering—which archaeologists did not realize that Native American communities might have. The site also reveals an emphasis on public works, rather than on war. So this discovery might rewrite a bit of history. Another interesting note: Shawnee remains from the time are typically of petite, graceful men—and robust, muscular women. So it was probably the women who built the water system. Which means even more history to rewrite.

 

Thanks for the minute for Scientific American's 60-Second Science. I'm Cynthia Graber.

There is a native American site in Ohio that appear to be a fault. But recent discoveries by archeologists at the University of Cincinnati showed that's not the case. Instead it's a 2000-year-old shorny water management system. It stretched out almost six kilometers. That's much larger than what had been thought to compromise the so-called fault. It's one of the largest subsides of the country. But what happened thought to be gates from military protection are actually a series of dams in irrigation canals. There are logs and *for damming, raised ways for flooding water orginated far away from spring. The water was stored and channeld for irrigation. Rock walls show water sediments and clay.

There is a native American site in Ohio that appear to be a fort. But recent discoveries by archiologists at the University of Saint Nati show that's not the case. Instead it's a 2000-year old shining water manage system. It dradges at almost six kilometers, that's much larger than what had been thought to comprise the so called fort. It's one of the largest such site in the country. What had been thought to be gates for military protection, are actually a series of dams XXX. There are logs and c for daming, raise way for flowing water originated far springs. The water where stored in channel were for arigation, drshow what claimed. The side dams are sophiscated engineering, which archiologitst not realized that native American communities might have. Beside, it also reveals emphasis on public works rather than one work. So these discoveries might rewrite a bit of history. Another interesting note? Shining remains are typically of for particular grace for men and robust must given women. So it was probably the women who built the water system, which means even more history to rewrite. Thanks for the minute for Scientific American Sixty Seconds Science. I'm Cynthia Graber.

Instead it's a 2000-year-old shorny water management system. It stretches out almost 6 kilometers. That’s much larger than what I have been thought to comprise the so-called fort.

There are logs and clay bricks for damming, race waves for flowing water originated in far off springs. The water was stored and channeled for irrigation, road records showed water sediments and clay.

 

The site demonstrates a sophisticated knowledge of engineering which archeologists not realized that Native American communities might have. The site also reviews emphasis on public works rather on the wall. So this just discovery might rewrite a bit of history. Another interesting note, shorny remains for the time are typically of petite graceful men and robust muscular women. So it would probably the women who build the water system, which means even more history to rewrite.
