3D Diorama Along the Trail of Tears

By William Ambrose

On the western side of the state of Missouri, the Trail of Tears is generally the Springfield to St. Louis Road.  The General Land Office (GLO) surveyors, those earliest government surveyors who surveyed the unsettled frontier lands ahead of any land sales, were required to draw the existing roads on the township plats beginning at about the time they surveyed the western half of Missouri.  The Springfield to St. Louis Road was pre-historic – it was a trace on the ground from Springfield to St. Louis used by Native Americans for travel for trade and hunting long before Americans arrived in the state.  The GLOs were the building blocks of President Jefferson’s rectilinear survey system, known as the Public Land Survey System, created by the Land Ordinance of 1785, a federal law. The system was laid out in 6-mile-by-6-mile squares, each square being known by its north-south “Township” number and its east-west “Range” number. 


Scott‘s

By William Ambrose

From 1837 to 1839, the Federal Government forcibly removed 17,000 Cherokees from their centuries-old homelands in Georgia, Tennessee, North and South Carolina, and Alabama.  The Cherokee families were rounded up at gunpoint by Federal troops, held prisoner in detention camps, divided up into detachments of about 1000 people, and then forced to walk the 1000 miles to “Indian Territory,” now Oklahoma. Approximately 4000 died during that process.
