The Chickasaw Bluffs were numbered by rivermen from one to four, starting from the north.

Pierre Prudhomme was assumed captured by Chickasaws. La Salle decided to stay and search for the missing member. La Salle had a stockade built and named it Fort Prudhomme, after their lost man. This was the first structure built by the French in Tennessee. Days later, the missing man found his way back to La Salle. Prudhomme had lost his way while hunting. The expedition reached the mouth of the Mississippi River on April 6, 1682. The exact location of Fort Prudhomme is unknown. Researchers agree that it was located on the Chickasaw Bluff but the site is disputed. Some historians claim that Fort Prudhomme was built on the first Chickasaw Bluff, in modern-day Lauderdale County. The ''Tennessee Encyclopedia of History and Culture'' suggests that the fort was constructed on the second Chickasaw Bluff near modern-day Randolph. Other research mentions the third Chickasaw Bluff as the location of the fort, at the border of modern Tipton and Shelby counties. The fourth Chickasaw Bluff in modern Shelby County at

is also supported as a site of Fort Prudhomme.
