Which river ran through the mississippian, adena, and hopewell culture areas?

The correct answer is - Ohio River.

The Mississippian culture, Adena culture, and Hopewell culture, were all native American cultures. They were set about big rivers which allowed them the conditions for prosper and development. The Mississippian culture and the Hopewell culture had pretty much the same territory, and they were mostly based around the Mississippi River but had territories along the shores of other rivers as well, but the Adena culture did not had an area with the Mississippi River, instead the Adena culture was based around the Ohio River. The Ohio River is actually the river that connects all three cultures because they all occupied territories around this river, while the Adena culture was totally based around it, the other two were only partially based around the Ohio River.
