The situation languished during the troubles in Kansas leading up to the Civil War. In the 1866 Cherokee Reconstruction treaty, the Cherokee agreed to cede, in trust to the United States, such portion of their land that is in present-day Kansas. A commission was set up to survey the disputed land. The survey, approved December 11, 1871, found that the border was "off by 2.46 miles". The strip in question ran from the Neosho River to the 100th meridian and amounted to 434,679.36 acres (1,759 km2).
