The locality is a level plat in a bend of the Des Moines River between Eldon and Iowaville, Wapello County. The plat of this area and the sites of the burial places, as shown in Fig. 9, are based upon the statements of Mr. J. H. Jordan (the person referred to), who has resided here since the close of the Black Hawk war, and was the agent of the Sacs and Foxes from their removal hither after the war until Black Hawk's death, September 15, 1838.[19] The extreme width of the area represented is about 2 miles. Close to the point of the bend formerly stood the agency building, near which is the present residence of Mr. Jordan. The triangle marks the position of Black Hawk's grave; the parallel lines, the race-tracks; the rings in the upper corner, the mounds of the Iowas; those in the lower corner, near Iowaville, the mounds of the Pottawattamies; and the open dots, near the same point, the place where the scaffolds for their dead stood. Mr. Jordan says: "This valley had long been a famous haunt for the warring Indians, but was, at the time of my first personal acquaintance with it, in possession of the Iowas, whose main village was around the point where my present residence now stands. The race-course consisted of three hard beaten parallel tracks nearly a mile in length, where the greater portion of the Iowa warriors were engaged in sport when Black Hawk surprised and slaughtered a great portion of them in 1830. After Black Hawk and his warriors had departed with their plunder, the remaining Iowas returned and buried their dead in little mounds of sod and earth, from 2 to 4 feet high, at the point indicated on the diagram. "After the Black Hawk war was over, the remnant of the Iowas, by treaty, formally ceded their rights in this valley to the Sacs and Foxes. At this place this noted chief was buried, in accordance with his dying request, in a full military suit given him by President Jackson, together with the various memorials received by him from the whites and the trophies won from the Indians. He was placed on his back on a 'puncheon' [split slab of wood], slanting at a low angle to the ground, where his feet were sustained by another, and then covered with several inches of sod. Over this was placed a roof-shaped covering of slabs or 'puncheons,' one end being higher than the other; over this was thrown a covering of earth and sod to the depth of a foot or more, and the whole surrounded by a line of pickets some 8 or 10 feet high." Here we have evidence that some at least of the Indians of this region were accustomed to bury their dead in mounds down to a recent date.
