A very interesting map that shows four versions of the disputed boundaries between Missouri and Iowa, including a related dispute over the Half Breeds Boundary for a tract of land between the Mississippi & Des Moines Rivers. Various versions of the two major lines, namely Brown's Line or Line claimed by Missouri and Old Indian Boundary or Sullivan's Line, are detailed. The Platte District annexation of 1836 is also delineated. Drawn by George A. Leakin. This is the second edition of the map, published in the report "Northern Boundary of Missouri."
