Fort Osage National Historic Landmark, in cooperation with the Missouri Society of Professional Surveyors, will host a commemoration of the 200th anniversary of Joseph C. Brown's survey of the Osage Treaty Line. As set forth in Missouri's original petition for statehood, this line was intended to serve as the western and northern boundaries of the state. It was initially negotiated during the 1808 treaty between the United States of America and chiefs of the Greater and Little Osage nations.
This line represents the first boundary line actually surveyed in western Missouri. The boundary line had two components, one on each side of the Missouri River. While the southern segment does not survive, the northern segment still serves as county and state boundaries. The effort to survey both of these lines originated at Fort Osage.
The commemoration will include demonstrations of surveying tools, dedication of a replica treaty line monument, and a reenactment of the running of the first leg of the line, with a cannon salute.
