Note I-52 — Chapter I · ITINERARY: ST. LOUIS TO ST. PAUL, AUGUST 9TH-SEPTEMBER 21ST, 1805.

By the river channel barely over the Iowa State line into Houston Co., Minn., obliquely opposite Tippet's landing, and about a mile below the mouth of Bad Axe r., which falls in on the Wisconsin side. Pike continues to have Wisconsin on his right until he crosses the mouth of St. Croix r.

I suspect that the Upper Iowa r., which Pike has just left, has a longer historical record than that with which it is generally credited. Franquelin, 1688, maps a large river above the Wisconsin and below Root r., thus apparently in the position of the Upper Iowa. He letters Indians on it as Peoueria and Tapoueri. Perrot's Ayoës r. seems to be the same, as is certainly the Ioua r. of Lewis and Clark's map, 1814. Long has Little Ioway r. in 1817, and Upper Iaway r. in 1823.
