Carver crossed to the Wisconsin River and then traveled down the Mississippi emerging at the great trade encampment at Prairie du Chien. Rather than turn south towards New Orleans, his expedition turned north into what is now Minnesota. By the late summer he had reached the Saint Anthony Falls at what is now Minneapolis. He spent some time with the tribe near the falls but turned south, down the Mississippi to find a more suitable place to spend the winter. During this portion of the trip he discovered Carver's Cave.
